Cognitive force of metaphor

A study of metaphors by mathematicians? An August 6, 2025 Max-Planck-Gesellschaft (Max Planck Institute for Mathematics in the Sciences) press release (also on EurekAlert but published August 27, 2025) answers some question about their work on metaphor theory,

  • Beyond Rhetoric: Metaphors are not just stylistic devices but stable linguistic and cognitive structures.
  • Mapping Meaning: Two key metaphorical processes link concrete and abstract concepts in a structured network.
  • Broad Impact: Findings have implications for linguistics, philosophy, AI, and the mathematics of cognition.

Metaphors are a fundamental aspect of human language and cognition, allowing us to understand complex concepts and relationships by mapping them onto more familiar and concrete domains. However, the nature of metaphors and how they work is still not well understood. In a new recent paper, published in PLOS Complex Systems, Max-Planck-Institute for Mathematics in the Sciences researchers Marie Teich and Wilmer Leal together with director Jürgen Jost have developed a formal framework and large-scale empirical methodology to analyze metaphors and their role in conceptual metaphor theory.

Key findings

The study confirms the fundamental assumption in conceptual metaphor theory that metaphors are enduring linguistic and cognitive structures, not merely rhetorical figures. Using complex systems tools, the researchers identified a metaphor network with distinctions between abstract and concrete categories, and two significant metaphorical processes: mappings from concrete to abstract topics and the emergence of new mappings between concrete domains. The study also found that metaphors concentrate on two small sets of everyday topics, with one within the concrete group serving as both strong source and target domains, and the other in the abstract group primarily acting as targets. These findings indicate that metaphor is a creative process driven by contrast and tension between topics which allow re-conceptualizations and the emergence of new similarities.

Implications and future research directions

The study’s findings have significant implications for researchers in cognitive linguistics and the philosophy of language, particularly those focused on conceptual metaphor theory, figurative language, and semantic structure. The large-scale empirical methodology proposed by the authors can be used to do fundamental research in Conceptual Metaphor Theory providing new insights into the nature of metaphor and figurative thinking.

Beyond the humanities, this work opens interesting research questions for machine learning and artificial intelligence, particularly in areas concerned with analogy and representation learning. The methods also hold promise for the mathematics of cognition and formal epistemology, offering tools to study how abstract meaning arises from structure-preserving mappings across conceptual domains.

Copyright, artificial intelligence, and thoughts about cyborgs

I’ve been holding this one for a while and now, it seems like a good followup to yesterday’s, October 20, 2025 posting about “AI and the Art of Being Human,” which touches on co-writing and my October 13, 2025 posting and its mention of “Who’s afraid of AI? Arts, Sciences , and the Futures of Intelligence,” a conference and arts festival at the University of Toronto (scroll down to the “Who’s Afraid of AI …” subhead).

With the advent of some of the latest advances in artificial intelligence (AI) and its use in creative content, the view on copyright (as a form of property) seems to be shifting. In putting this post together I’ve highlighted a blog posting that focuses on copyright and AI as it is commonly viewed. Following that piece, is a look at N. Katherine Hayles’ concept of AI as one of a number of cognitive assemblages and the implications of that concept where AI and copyright are concerned.

Then, it gets more complicated. What happens when your neural implant has an AI component? It’s question asked by members of a Canadian legal firm, McMillan LLP, a business law firm in their investigation of copyright. (The implication of this type of cognitive assemblage is not explicitly considered in Hayles’ work.) Following on the idea of a neural implant enhanced with AI, cyborg bugs (they too can have neural implants) are considered.

Uncomplicated vision of AI and copyright future

Glyn Moody’s May 15, 2025 posting on techdirt.com provides a very brief overview of the last 100 years of copyright and goes on to highlight some of the latest AI comments from tech industry titans, Note: Links have been removed,

For the last hundred years or so, the prevailing dogma has been that copyright is an unalloyed good [emphasis mine], and that more of it is better. Whether that was ever true is one question, but it is certainly not the case since we entered the digital era, for reasons explained at length in Walled Culture the book (free digital versions available). Despite that fact, recent attempts to halt the constant expansion and strengthening of copyright have all foundered. Part of the problem is that there has never been a constituency with enough political clout to counter the huge power of the copyright industry and its lobbyists.

Until now. The latest iteration of artificial intelligence has captured the attention of politicians around the world [emphasis mine]. It seems that the latter can’t do enough to promote and support it, in the hope of deriving huge economic benefits, both directly, in the form of local AI companies worth trillions, and indirectly, through increased efficiency and improved services. That current favoured status has given AI leaders permission to start saying the unsayable: that copyright is an obstacle to progress [emphasis mine], and should be reined in, or at least muzzled, in order to allow AI to reach its full potential. …

In its own suggestions for the AI Action Plan, Google spells out what this means:

Balanced copyright rules, such as fair use and text-and-data mining exceptions, have been critical to enabling AI systems to learn from prior knowledge and publicly available data, unlocking scientific and social advances. These exceptions allow for the use of copyrighted, publicly available material for AI training without significantly impacting rightsholders and avoid often highly unpredictable, imbalanced, and lengthy negotiations with data holders during model development or scientific experimentation. Balanced copyright laws that ensure access to publicly available scientific papers, for example, are essential for accelerating AI in science, particularly for applications that sift through scientific literature for insights or new hypotheses.

… some of the biggest personalities in the tech world have gone even further, reported here by TechCrunch:

Jack Dorsey, co-founder of Twitter (now X) and Square (now Block), sparked a weekend’s worth of debate around intellectual property, patents, and copyright, with a characteristically terse post declaring, “delete all IP law.”

X’s current owner, Elon Musk, quickly replied, “I agree.”

It’s not clear what exactly brought these comments on, but they come at a time when AI companies, including OpenAI (which Musk co-founded, competes with, and is challenging in court), are facing numerous lawsuits alleging that they’ve violated copyright to train their models.

Unsurprisingly, that bold suggestion provoked howls of outrage from various players in the copyright world. That was to be expected. But the fact that big names like Musk and Dorsey were happy to cause such a storm is indicative of the changed atmosphere in the world of copyright and beyond. Indeed, there are signs that the other main intellectual monopolies – patents and trademarks – are also under pressure. Calling into question the old ways of doing things in these fields will also weaken the presumption that copyright must be preserved in its current state.

Yes, it is interesting to see tech moguls such as Jack Dorsey and Elon Musk take a more ‘enlightened’ approach to copyright. However, there may be a few twists and turns to this story as it continues to develop..

Copyright and cognitive assemblages

I need to set the stage with something coming from N. Katherine Hayles’ 2025 book “Bacteria to AI; Human Futures with our Nonhuman Symbionts.” She suggests that we (humans) will be members in cognitive assemblages including bacteria, plants, cells, AI, and more. She then decouples cognition from consciousness and claims entities such as bacteria, etc. are capable of ‘nonconscious cognition’.

Hayles avoids the words ‘thinking’ and ‘thought’ by using cognition and providing this meaning for the word,

… “cognition is a process that interprets information within contexts that connect it with meaning” (Hayles 2017, 22 [in “Unthought: The power of the Cognitive Nonconscious”‘ University of Chicago Press]) Note: Hayles quotes herself on pp. 8-9 in 2025’s “Bacteria to AI ..”

Hayles then develops the notion of a cognitive assemblage made up of conscious (e.g. human) and nonconscious (e.g. AI agent) cognitions. The part that most interests me is where Hayles examines copyright and cognitive assemblages,

.. what happens to the whole idea of intellectual property when an AI has perused copyrighted works during its training and incorporated them into its general sense of how to produce a picture of X or a poem about Y. Already artists and stakeholders are confronting similar issues in the age of remixing and modifying existing content. how much of a picture, or a song, needs to be altered for it not to count as copyright infringement? As legal cases like this work their way through the courts, collective intelligence will doubt continue to spread through the cultures of developed countries, as more and more people come to rely on ChatGPT and similar models for more and more tasks. Thus our cultures edge toward the realization that the very idea of intellectual property as something owned by an individual who has exclusive rights to it may need to be rethought [emphasis mine] and reconceptualized on a basis consistent with the reality of collective intelligence [emphasis mine] and the pervasiveness of cognitive assemblages in producing products of value in the contemporary era. [pp. 226 – 227 in Hayles’ 2025 book, “Bacteria to AI …]

It certainly seems as if the notion of intellectual property as personal property is being seriously challenged (and not by academics alone) but this state of affairs may be temporary. In particular, the tech titans see a benefit to loosening the rules now but what happens if they see an advantage to tightening the rules?

Neurotechnology, AI, and copyright

Neuralink states clearly that AI is part of their (and presumably other company’s) products, from the “Neuralink and AI: Bridging the Gap Between Humans and Machines,” Note: Links have been removed,

The intersection of artificial intelligence (AI) and human cognition is no longer a distant sci-fi dream—it’s rapidly becoming reality. At the forefront of this revolution is Neuralink, a neurotechnology company founded by Elon Musk in 2016, dedicated to creating brain-computer interfaces (BCIs) that seamlessly connect the human brain to machines. With AI advancing at an unprecedented pace, Neuralink aims to bridge the gap between humans and technology, offering transformative possibilities for healthcare, communication, and even human evolution. In this article, we’ll explore how Neuralink and AI are reshaping our future, the science behind this innovation, its potential applications, and the ethical questions it raises.

Robbie Grant, Yue Fei, and Adelaide Egan (plus Articling Students: Aki Kamoshida and Sara Toufic) have given their April 17, 2025 article for McMillan LLP, a Canadian business law firm, a (I couldn’t resist the wordplay) ‘thought provoking’ title, “Who Owns a Thought? Navigating Legal Issues in Neurotech” for a very interesting read, Note 1: Links have been removed, Note 2: I’ve included the numbers for the footnotes but not the footnotes themselves,

The ongoing expansion of Neurotechnology (or “neurotech”) for consumers is raising questions related to privacy and ownership of one’s thoughts, as well as what will happen when technology can go beyond merely influencing humans and enter the realm of control {emphasis mine}.

Last year, a group of McGill students built a mind-controlled wheelchair in just 30 days.[1] Brain2Qwerty, Meta’s neuroscience project which translates brain activity into text, claims to allow for users to “type” with their minds.[2] Neuralink, a company founded by Elon Musk {emphasis mine}, is beginning clinical trials in Canada testing a fully wireless, remotely controllable device to be inserted into a user’s brain {emphasis mine}.[3] This comes several years after the company released a video of a monkey playing videogames with its mind using a similar implantable device.

The authors have included a good description of neurotech, from their April 17, 2025 article,

Neurotech refers to technology that records, analyzes or modifies the neurons in the human nervous system. Neurotech can be broken down into three subcategories:

    Neuroimaging: technology that monitors brain structure and function;

    Neuromodulation: technology that influences brain function; and

    Brain-Computer Interfaces or “BCIs”: technology that facilitates direct communication between the brain’s electrical activity and an external device, sometimes referred to as brain-machine interfaces.[5]

In the medical and research context, neurotech has been deployed for decades in one form or another. Neuroimaging techniques such as EEG, MRI and PET have been used to study and analyze brain activity.[6] Neuromodulation has also been used for the treatment of various diseases, such as for deep brain stimulation for Parkinson’s disease[7] as well as for cochlear implants.[8] However, the potential for applications of neurotech beyond medical devices is a newer development, accelerated by the arrival of less intrusive neurotech devices, and innovations in artificial intelligence.

My interests here are not the same as the authors’, the focus in this posting is solely on intellectual property, from their April 17, 2025 article,

3.  Intellectual Property

As neurotech continues to advance, it is possible that it will be able to make sense of complex, subconscious data such as dreams. This will present a host of novel IP challenges, which stem from the unique nature of the data being captured, the potential for the technology to generate new insights, and the fundamental questions about ownership and rights in a realm where personal thoughts become part of the technological process.

Ownership of Summarized Data: When neurotech is able to capture subconscious thoughts, [emphasis mine] it will likely process this data into summaries that reflect aspects of an individual’s mental state. The ownership of such summaries, however, can become contentious. On the one hand, it could be argued that the individual, as the originator of their thoughts, should own the summaries. On the other hand, one could argue that the summaries would not exist but for the processing done by the technology and hence the summaries should not be owned (or exclusively owned) by the individual. The challenge may be in determining whether the summary is a transformation of the data that makes it the product of the technology, or whether it remains simply a condensed version of the individual’s thoughts, in which case it makes sense for the individual to retain ownership.

Ownership of Creative Outputs: The situation becomes more complicated if the neurotech produces creative outputs based on the subconscious thoughts captured by the technology. For example, if the neurotech uses subconscious imagery or emotions to create art, music, or other works, who owns the rights to these works? Is the individual whose thoughts were analyzed the creator of the work, or does the technology, which has facilitated and interpreted those thoughts, hold some ownership? This issue is especially pertinent in a world where AI-generated creations are already challenging traditional ideas of IP ownership. For example, in many jurisdictions, ownership of copyrightable works is tied to the individual who conceived them.[27] Uncertainty can arise in cases where works are created with neurotech, where the individual whose thoughts are captured may not be aware of the process, or their thoughts may have been altered or combined with other information to produce the works. These uncertainties could have significant implications for IP ownership, compensation, and the extent to which individuals can control or profit from the thoughts embedded in their own subconscious minds.

The reference to capturing data from subconscious thought and how that might be used in creative outputs is fascinating. This sounds like a description of one of Hayles’ cognitive assemblages with the complicating factor of a technology that is owned by a company. (Will Elon Musk be quite so cavalier about copyright when he could potentially own your thoughts and, consequently, your creative output?)

If you have the time (it’s an 11 minute read according to the authors), the whole April 17, 2025 article is worth it as the authors cover more issues (confidentiality, Health Canada oversight, etc.) than I have included here.

I also stumbled across the issue of neurotech tech companies and ownership of brain data (not copyright but you can see how this all begins to converge) in a February 29, 2024 posting “Portable and non-invasive (?) mind-reading AI (artificial intelligence) turns thoughts into text and some thoughts about the near future” where I featured this quote (scroll down about 70% of the way),

Huth [Alexander Huth, assistant professor of Neuroscience and Computer Science at the University of Texas at Austin] and Tang [Jerry Tang, PhD student in the Department of Computer Science at the University of Texas Austin] concluded that brain data, therefore, should be closely guarded, especially in the realm of consumer products. In an article on Medium from last April, Tang wrote that “decoding technology is continually improving, and the information that could be decoded from a brain scan a year from now may be very different from what can be decoded today. It is crucial that companies are transparent about what they intend to do with brain data and take measures to ensure that brain data is carefully protected.” (Yuste [Rafael Yuste, a Columbia University neuroscientist] said the Neurorights Foundation recently surveyed the user agreements of 30 neurotech companies and found that all of them claim ownership of users’ brain data — and most assert the right to sell that data to third parties. [emphases mine]) Despite these concerns, however, Huth and Tang maintained that the potential benefits of these technologies outweighed their risks, provided the proper guardrails [emphasis mine] were put in place.

While I’m still with neurotech, there’s another aspect to be considered as noted in my April 5, 2022 posting “Going blind when your neural implant company flirts with bankruptcy (long read).” My long read is probably 15 mins. or more.

Ending on a neurotech device/implant note, here’s a November 20, 2024 University Hospital Network (UHN) news release burbling happily about their new clinical trial involving Neurolink

UHN is proud to be selected as the first hospital in Canada to perform a pioneering neurosurgical procedure involving the Neuralink implantable device as part of the CAN-PRIME study, marking a significant milestone in the field of medical innovation.

This first procedure in Canada represents an exciting new research direction in neurosurgery and will involve the implantation of a wireless brain-computer interface (BCI) at UHN’s Toronto Western Hospital, the exclusive surgical site in Canada.

“We are incredibly proud to be at the forefront of this research advancement in neurosurgery,” says Dr. Kevin Smith, UHN’s President and CEO. “This progress is a testament to the dedication and expertise of our world-leading medical and research professionals, as well as our commitment to providing the most innovative and effective treatments for patients.

“As the first and exclusive surgical site in Canada to perform this procedure, we will be continuing to shape the future of neurological care and further defining our track record for doing what hasn’t been done.”

Neuralink has received Health Canada approval to begin recruiting for this clinical trial in Canada.

The goal of the CAN-PRIME Study (short for Canadian Precise Robotically Implanted Brain-Computer Interface), according to the study synopsis, is “to evaluate the safety of our implant (N1) and surgical robot (R1) and assess the initial functionality of our BCI for enabling people with quadriplegia to control external devices with their thoughts [emphasis mine].”

Patients with limited or no ability to use both hands due to cervical spinal cord injury or amyotrophic lateral sclerosis (ALS), may be eligible for the CAN-PRIME Study.

“This landmark surgery has the potential to transform and improve outcomes for patients who previously had limited options,” says Dr. Andres Lozano, the Alan and Susan Hudson Cornerstone Chair in Neurosurgery at UHN and lead of the CAN-PRIME study at UHN.

The procedure, which combines state-of-the-art technology and advanced surgical techniques, will be carried out by a multidisciplinary team of neurosurgeons, neuroscientists and medical experts at UHN.

“This is a perfect example of how scientific discovery, technological innovation, and clinical expertise come together to develop new approaches to continuously improve patient care,” says Dr. Brad Wouters, Executive Vice President of Science & Research at UHN. “As Canada’s No. 1 research hospital, we are proud to be leading this important trial in Canada that has the goal to improve the lives of individuals living with quadriplegia or ALS.”

The procedure has already generated significant attention within the medical community and further studies are planned to assess its long-term effectiveness and safety.

UHN is recognized for finding solutions beyond boundaries, achieving firsts and leading the development and implementation of the latest breakthroughs in health care to benefit patients across Canada, and around the world.

Not just human brains: cyborg bugs and other biohybrids

Brain-computer interfaces don’t have to be passively accepting instructions from humans, they could also be giving instructions to humans. I don’t have anything that makes the possibility explicit except by inference. For example, let’s look at cyborg bugs, from a May 13, 2025 article “We can turn bugs into flying, crawling RoboCops. Does that mean we should” by Carlyn Zwarenstein for salon.com, Note: Links have been removed,

Imagine a tiny fly-like drone with delicate translucent wings and multi-lensed eyes, scouting out enemies who won’t even notice it’s there. Or a substantial cockroach-like robot, off on a little trip to check out a nuclear accident, wearing a cute little backpack, fearless, regardless of what the Geiger counter says. These little engineered creatures might engage in search and rescue — surveillance, environmental or otherwise — inspecting dangerous areas you would not want to send a human being into, like a tunnel or building that could collapse at any moment, or a facility where there’s been a gas leak.

These robots are blazing new ethical terrain. That’s because they are not animals performing tasks for humans, nor are they robots that draw inspiration from nature. The drone that looks like a fly is both machine and bug. The Madagascar hissing cockroach robot doesn’t just perfectly mimic the attributes that allow cockroaches to withstand radiation and poisonous air: it is a real life animal, and it is also a mechanical creature controlled remotely. These are tiny cyborgs, though even tinier ones exist, involving microbes like bacteria or even a type of white blood cell. Like fictional police officer Alex Murphy who is remade into RoboCop, these real-life cyborgs act via algorithms rather than free will.

Even as the technology for the creation of biohybrids, of which cyborgs are just the most ethically fraught category, has advanced in leaps and bounds, separate research on animal consciousness has been revealing the basis for considering insects just as we might other animals. (If you look at a tree of life, you will see that insects are indeed animals and therefore share part of our evolutionary history: even our nervous systems are not completely alien to theirs). Do we have the right to turn insects into cyborgs that we can control to do our bidding, including our military bidding, if they feel pain or have preferences or anxieties?

… the boundaries that keep an insect — a hawkmoth or cockroach, in one such project — under human control can be invisibly and automatically generated from the very backpack it wears, with researchers nudging it with neurostimulation pulses to guide it back within the boundaries of its invisible fence if it tries to stray away.

As a society, you can’t really say we’ve spent significant time considering the ethics of taking a living creature and using it literally as a machine, although reporter Ariel Yu, reviewing some of the factors to take into account in a 2024 story inspired by the backpack-wearing roaches, framed the ethical dilemma not in terms of the use of an animal as a machine — you could say using an ox to pull a cart is doing that — but specifically the fact that we’re now able to take direct control of an animal’s nervous system. Though as a society we haven’t really talked this through either, within the field of bioengineering, researchers are giving it some attention.

If it can be done to bugs and other creatures, why not us (ethics???)

The issues raised in Zwarenstein’s article could also be applied to humans. Given how I started this piece, ‘who owns a thought’ could become where did the thought come from? Could a brain-computer interface (BCI) enabled by AI be receiving thoughts from someone other than the person who has it implanted in their brain? And, if you’re the one with the BCI, how would you know? In short, could your BCI or other implant be hacked? That’s definitely a possibility researchers at Rice University (Texas, US) have prepared for according to my March 27, 2025 posting, “New security protocol to protect miniaturized wireless medical implants from cyberthreats.”

Even with no ‘interference’ and begging the question of corporate ownership, if all the thoughts weren’t ‘yours’, would you still be you?

Symbiosis and your implant

I have a striking excerpt from a September 17, 2020 post (Turning brain-controlled wireless electronic prostheses into reality plus some ethical points),

This was the most recent and most directly applicable work that I could find. From a July 24, 2019 article by Liam Drew for Nature Outlook: The brain,

“It becomes part of you,” Patient 6 said, describing the technology that enabled her, after 45 years of severe epilepsy, to halt her disabling seizures. Electrodes had been implanted on the surface of her brain that would send a signal to a hand-held device when they detected signs of impending epileptic activity. On hearing a warning from the device, Patient 6 knew to take a dose of medication to halt the coming seizure.

“You grow gradually into it and get used to it, so it then becomes a part of every day,” she told Frederic Gilbert, an ethicist who studies brain–computer interfaces (BCIs) at the University of Tasmania in Hobart, Australia. “It became me,” she said. [emphasis mine]

Gilbert was interviewing six people who had participated in the first clinical trial of a predictive BCI to help understand how living with a computer that monitors brain activity directly affects individuals psychologically1. Patient 6’s experience was extreme: Gilbert describes her relationship with her BCI as a “radical symbiosis”.

Symbiosis is a term, borrowed from ecology, that means an intimate co-existence of two species for mutual advantage. As technologists work towards directly connecting the human brain to computers, it is increasingly being used to describe humans’ potential relationship with artificial intelligence.

Interface technologies are divided into those that ‘read’ the brain to record brain activity and decode its meaning, and those that ‘write’ to the brain to manipulate activity in specific regions and affect their function.

Commercial research is opaque, but scientists at social-media platform Facebook are known to be pursuing brain-reading techniques for use in headsets that would convert users’ brain activity into text. And neurotechnology companies such as Kernel in Los Angeles, California, and Neuralink, founded by Elon Musk in San Francisco, California, predict bidirectional coupling in which computers respond to people’s brain activity and insert information into their neural circuitry. [emphasis mine]

This isn’t the first time I’ve used that excerpt or the first time I’ve waded into the ethics question regarding implants. For the curious, I mentioned the April 5, 2022 post “Going blind when your neural implant company flirts with bankruptcy (long read)” earlier and there’s a February 23, 2024 post “Neural (brain) implants and hype (long read)” as well as others.

So, who does own a thought?

Hayles’ notion of assemblages puts into question the notion of a ‘self’ or, if you will, an ‘I’. (Segue: Hayles will be in Toronto for the Who’s Afraid of AI? Arts, Sciences, and the Futures of Intelligence conference, October 23 – 24, 2025.) More questions have been raised with some of the older research about our relationships with AI: (1) see my December 3, 2021 posting “True love with AI (artificial intelligence): The Nature of Things explores emotional and creative AI (long read)” and newer research (2) see my upcoming post “A collaborating robot as part of your “extended” body.”

While I seem to have wandered into labyrinthine philosophical questions, I suspect lawyers will work towards more concrete definitions so that any questions that arise such as ‘who owns a thought’ can be argued and resolved in court.

Help maintain cognitive and memory functions with virtual reality (VR) game which integrates smell

I always enjoy a research story involving the sense of smell (olfaction); the most recent ones here being an April 22, 2025 posting (also from the Institute of Science Tokyo) “Fragrance design using deep neural networks (DNNs)” and an April 17, 2025 posting “Olfactory ethics.” There’s also this ‘golden oldie’ from May 22, 2017 “Preserving heritage smells (scents).” Now, the sense of smell enters virtual reality.

Caption: Olfactory VR offers the potential for cognitive rehabilitation and dementia preventation [sic] in aging populations Credit: Institute of Science Tokyo

An April 30, 2025 Institute of Science Tokyo press release (also on EurekAlerrt) describes some of the latest investigation into the sense of smell, Note: A link has been removed,

As the global population ages, supporting older adults in maintaining their cognitive and memory functions has become a pressing concern. The United Nations estimates that by the 2070s, there will be over 2.2 billion people aged 65 or older, surpassing the global number of children under 18. This demographic shift is especially pronounced in Japan, the fastest-aging country, where 28.7% of the population is 65 or older.

One promising strategy to counter cognitive decline is through olfactory stimulation—engaging the sense of smell. Smell signals travel directly to brain regions involved in memory and emotion. Building on this knowledge, a joint research team from Institute of Science Tokyo (Science Tokyo), University of the Arts London, Bunkyo Gakuin University, and Hosei University, Japan, has developed the world’s first cognitive training method for older adults by combining olfactory stimulation with virtual reality (VR). The study was published in Volume 15 of the journal Scientific Reports on March 28, 2025.

“VR provides a promising platform to simulate sensory conditions in a controlled yet engaging manner. By combining goal-oriented tasks with real-time feedback, our VR-based olfactory training approach can increase cognitive engagement and maximize its therapeutic impact,” says Professor Takamichi Nakamoto from Science Tokyo.

The method involves an olfactory display that emits specific scents during immersive VR gameplay, activating memory- and emotion-related brain regions. In the activity, participants are asked to memorize and later match scents within a virtual environment. The experience begins in a virtual landscape. Using a VR controller, participants interact with a scent source represented by a stone statue. When touched, the statue releases a specific scent, accompanied by a white vapor cloud as a visual cue to reinforce memory.

Participants then explore the virtual landscape to locate a scent source. As they move through the landscape, the olfactory display emits subtle traces of the scent to guide them to the location. Upon reaching the odor source, shown as a stone lantern, they encounter three colored vapor clouds, each emitting a different scent. Their task is to compare the smells and identify the one that matches the original scent they memorized.

“The smell memory phase strengthens odor recognition and memory encoding by linking the olfactory stimulus with a visual cue. The navigation phase challenges players to integrate spatial navigation with odor recognition while retaining memory of the initial scent. The final odor comparison phase engages olfactory discrimination and working memory retrieval, reinforcing cognitive function,” explains Nakamoto.

The activity led to noticeable cognitive improvements in 30 older adults aged 63 to 90. After just 20 minutes of playing the VR game, participants showed improvements in visuospatial rotation and memory. Visuospatial processing and cognitive function were assessed through different tasks. In the Hiragana Rotation Task, where they had to decide if rotated Japanese characters matched the original, scores improved from 19–82 to 29–85. In a word-based spatial memory recall task, where participants memorized word positions in a grid, scores rose from 0­–15 to 3–15. These improvements were validated through statistical analysis.

With continued research and development toward more affordable olfactory displays or alternate scent delivery methods, olfactory-based VR activities could become an accessible and engaging tool for supporting mental health in older adults.

Using copyright to shut down easy access to scientific research

This started out as a simple post on copyright and publishers vis à vis Sci-Hub but then John Dupuis wrote a think piece (with which I disagree somewhat) on the situation in a Feb. 22, 2016 posting on his blog, Confessions of a Science Librarian. More on Dupuis and my take on it after a description of the situation.

Sci-Hub

Before getting to the controversy and legal suit, here’s a preamble about the purpose for copyright as per the US constitution from Mike Masnick’s Feb. 17, 2016 posting on Techdirt,

Lots of people are aware of the Constitutional underpinnings of our copyright system. Article 1, Section 8, Clause 8 famously says that Congress has the following power:

To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries.

We’ve argued at great length over the importance of the preamble of that section, “to promote the progress,” but many people are confused about the terms “science” and “useful arts.” In fact, many people not well-versed in the issue often get the two backwards and think that “science” refers to inventions, and thus enables a patent system, while “useful arts” refers to “artistic works” and thus enables the copyright system. The opposite is actually the case. “Science” at the time the Constitution was written was actually synonymous with “learning” and “education” (while “useful arts” was a term meaning invention and new productivity tools).

While over the centuries, many who stood to benefit from an aggressive system of copyright control have tried to rewrite, whitewash or simply ignore this history, turning the copyright system falsely into a “property” regime, the fact is that it was always intended as a system to encourage the wider dissemination of ideas for the purpose of education and learning. The (potentially misguided) intent appeared to be that by granting exclusive rights to a certain limited class of works, it would encourage the creation of those works, which would then be useful in educating the public (and within a few decades enter the public domain).

Masnick’s preamble leads to a case where Elsevier (Publishers) has attempted to halt the very successful Sci-Hub, which bills itself as “the first pirate website in the world to provide mass and public access to tens of millions of research papers.” From Masnick’s Feb. 17, 2016 posting,

Rightfully, this is being celebrated as a massive boon to science and learning, making these otherwise hidden nuggets of knowledge and science that were previously locked up and hidden away available to just about anyone. And, to be clear, this absolutely fits with the original intent of copyright law — which was to encourage such learning. In a very large number of cases, it is not the creators of this content and knowledge who want the information to be locked up. Many researchers and academics know that their research has much more of an impact the wider it is seen, read, shared and built upon. But the gatekeepers — such as Elsveier and other large academic publishers — have stepped in and demanded copyright, basically for doing very little.

They do not pay the researchers for their work. Often, in fact, that work is funded by taxpayer funds. In some cases, in certain fields, the publishers actually demand that the authors of these papers pay to submit them. The journals do not pay to review the papers either. They outsource that work to other academics for “peer review” — which again, is unpaid. Finally, these publishers profit massively, having convinced many universities that they need to subscribe, often paying many tens or even hundreds of thousands of dollars for subscriptions to journals that very few actually read.

Simon Oxenham of the Neurobonkers blog on the big think website wrote a Feb. 9 (?), 2016 post about Sci-Hub, its originator, and its current legal fight (Note: Links have been removed),

On September 5th, 2011, Alexandra Elbakyan, a researcher from Kazakhstan, created Sci-Hub, a website that bypasses journal paywalls, illegally providing access to nearly every scientific paper ever published immediately to anyone who wants it. …

This was a game changer. Before September 2011, there was no way for people to freely access paywalled research en masse; researchers like Elbakyan were out in the cold. Sci-Hub is the first website to offer this service and now makes the process as simple as the click of a single button.

As the number of papers in the LibGen database expands, the frequency with which Sci-Hub has to dip into publishers’ repositories falls and consequently the risk of Sci-Hub triggering its alarm bells becomes ever smaller. Elbakyan explains, “We have already downloaded most paywalled articles to the library … we have almost everything!” This may well be no exaggeration. Elsevier, one of the most prolific and controversial scientific publishers in the world, recently alleged in court that Sci-Hub is currently harvesting Elsevier content at a rate of thousands of papers per day. Elbakyan puts the number of papers downloaded from various publishers through Sci-Hub in the range of hundreds of thousands per day, delivered to a running total of over 19 million visitors.

In one fell swoop, a network has been created that likely has a greater level of access to science than any individual university, or even government for that matter, anywhere in the world. Sci-Hub represents the sum of countless different universities’ institutional access — literally a world of knowledge. This is important now more than ever in a world where even Harvard University can no longer afford to pay skyrocketing academic journal subscription fees, while Cornell axed many of its Elsevier subscriptions over a decade ago. For researchers outside the US’ and Western Europe’s richest institutions, routine piracy has long been the only way to conduct science, but increasingly the problem of unaffordable journals is coming closer to home.

… This was the experience of Elbakyan herself, who studied in Kazakhstan University and just like other students in countries where journal subscriptions are unaffordable for institutions, was forced to pirate research in order to complete her studies. Elbakyan told me, “Prices are very high, and that made it impossible to obtain papers by purchasing. You need to read many papers for research, and when each paper costs about 30 dollars, that is impossible.”

While Sci-Hub is not expected to win its case in the US, where one judge has already ordered a preliminary injunction making its former domain unavailable. (Sci-Hub moved.) Should you be sympathetic to Elsevier, you may want to take this into account (Note: Links have been removed),

Elsevier is the world’s largest academic publisher and by far the most controversial. Over 15,000 researchers have vowed to boycott the publisher for charging “exorbitantly high prices” and bundling expensive, unwanted journals with essential journals, a practice that allegedly is bankrupting university libraries. Elsevier also supports SOPA and PIPA, which the researchers claim threatens to restrict the free exchange of information. Elsevier is perhaps most notorious for delivering takedown notices to academics, demanding them to take their own research published with Elsevier off websites like Academia.edu.

The movement against Elsevier has only gathered speed over the course of the last year with the resignation of 31 editorial board members from the Elsevier journal Lingua, who left in protest to set up their own open-access journal, Glossa. Now the battleground has moved from the comparatively niche field of linguistics to the far larger field of cognitive sciences. Last month, a petition of over 1,500 cognitive science researchers called on the editors of the Elsevier journal Cognition to demand Elsevier offer “fair open access”. Elsevier currently charges researchers $2,150 per article if researchers wish their work published in Cognition to be accessible by the public, a sum far higher than the charges that led to the Lingua mutiny.

In her letter to Sweet [New York District Court Judge Robert W. Sweet], Elbakyan made a point that will likely come as a shock to many outside the academic community: Researchers and universities don’t earn a single penny from the fees charged by publishers [emphasis mine] such as Elsevier for accepting their work, while Elsevier has an annual income over a billion U.S. dollars.

As Masnick noted, much of this research is done on the public dime (i. e., funded by taxpayers). For her part, Elbakyan has written a letter defending her actions on ethical rather than legal grounds.

I recommend reading the Oxenham article as it provides details about how the site works and includes text from the letter Elbakyan wrote.  For those who don’t have much time, Masnick’s post offers a good précis.

Sci-Hub suit as a distraction from the real issues?

Getting to Dupuis’ Feb. 22, 2016 posting and his perspective on the situation,

My take? Mostly that it’s a sideshow.

One aspect that I have ranted about on Twitter which I think is worth mentioning explicitly is that I think Elsevier and all the other big publishers are actually quite happy to feed the social media rage machine with these whack-a-mole controversies. The controversies act as a sideshow, distracting from the real issues and solutions that they would prefer all of us not to think about.

By whack-a-mole controversies I mean this recurring story of some person or company or group that wants to “free” scholarly articles and then gets sued or harassed by the big publishers or their proxies to force them to shut down. This provokes wide outrage and condemnation aimed at the publishers, especially Elsevier who is reserved a special place in hell according to most advocates of openness (myself included).

In other words: Elsevier and its ilk are thrilled to be the target of all the outrage. Focusing on the whack-a-mole game distracts us from fixing the real problem: the entrenched systems of prestige, incentive and funding in academia. As long as researchers are channelled into “high impact” journals, as long as tenure committees reward publishing in closed rather than open venues, nothing will really change. Until funders get serious about mandating true open access publishing and are willing to put their money where their intentions are, nothing will change. Or at least, progress will be mostly limited to surface victories rather than systemic change.

I think Dupuis is referencing a conflict theory (I can’t remember what it’s called) which suggests that certain types of conflicts help to keep systems in place while apparently attacking those systems. His point is well made but I disagree somewhat in that I think these conflicts can also raise awareness and activate people who might otherwise ignore or mindlessly comply with those systems. So, if Elsevier and the other publishers are using these legal suits as diversionary tactics, they may find they’ve made a strategic error.

ETA April 29, 2016: Sci-Hub does seem to move around so I’ve updated the links so it can be accessed but Sci-Hub’s situation can change at any moment.
