US National Academies Sept. 22-23, 2022 workshop on techno, legal & ethical issues of brain-machine interfaces (BMIs)

If you’ve been longing for an opportunity to discover more and to engage in discussion about brain-machine interfaces (BMIs) and their legal, technical, and ethical issues, an opportunity is just a day away. From a September 20, 2022 (US) National Academies of Sciences, Engineering, and Medicine (NAS/NASEM or National Academies) notice (received via email),

Sept. 22-23 [2022] Workshop Explores Technical, Legal, Ethical Issues Raised by Brain-Machine Interfaces [official title: Brain-Machine and Related Neural Interface Technologies: Scientific, Technical, Ethical, and Regulatory Issues – A Workshop]

Technological developments and advances in understanding of the human brain have led to the development of new Brain-Machine Interface technologies. These include technologies that “read” the brain to record brain activity and decode its meaning, and those that “write” to the brain to manipulate activity in specific brain regions. Right now, most of these interface technologies are medical devices placed inside the brain or other parts of the nervous system – for example, devices that use deep brain stimulation to modulate the tremors of Parkinson’s disease.

But tech companies are developing mass-market wearable devices that focus on understanding emotional states or intended movements, such as devices used to detect fatigue, boost alertness, or enable thoughts to control gaming and other digital-mechanical systems. Such applications raise ethical and legal issues, including risks that thoughts or mood might be accessed or manipulated by companies, governments, or others; risks to privacy; and risks related to a widening of social inequalities.

A virtual workshop [emphasis mine] hosted by the National Academies of Sciences, Engineering, and Medicine on Sept. 22-23 [2022] will explore the present and future of these technologies and the ethical, legal, and regulatory issues they raise.

The workshop will run from 12:15 p.m. to 4:25 p.m. ET on Sept. 22 and from noon to 4:30 p.m. ET on Sept. 23. View agenda and register.

For those who might want a peak at the agenda before downloading it, I have listed the titles for the sessions (from my downloaded Agenda, Note: I’ve reformatted the information; there are no breaks, discussion periods, or Q&As included),

2:05 pm ET Brain-Machine and Related Neural Interface Technologies: Reading and Writing the Brain for Thought, Communication, and Memory

4:00 pm ET Concluding Thoughts from Workshop Planning Committee

Regarding terminology, there’s brain-machine interface (BMI), which I think is a more generic term that includes: brain-computer interface (BCI), neural interface and/or neural implant. There are other terms as well, including this one in the title of my September 17, 2020 posting, “Turning brain-controlled wireless electronic prostheses [emphasis mine] into reality plus some ethical points.” I have a more recent April 5, 2022 posting, which is a very deep dive, “Going blind when your neural implant company flirts with bankruptcy (long read).” As you can see, various social issues associated with these devices have been of interest to me.

I’m not sure quite what to make of the session titles. There doesn’t seem to be all that much emphasis on ethical and legal issues but perhaps that’s the role the various speakers will play.

The Internet of Bodies and Ghislaine Boddington

I stumbled across this event on my Twitter feed (h/t @katepullinger; Note: Kate Pullinger is a novelist and Professor of Creative Writing and Digital Media, Director of the Centre for Cultural and Creative Industries [CCCI] at Bath Spa University in the UK).

Anyone who visits here with any frequency will have noticed I have a number of articles on technology and the body (you can find them in the ‘human enhancement’ category and/or search fro the machine/flesh tag). Boddington’s view is more expansive than the one I’ve taken and I welcome it. First, here’s the event information and, then, a link to her open access paper from February 2021.

Boddington’s paper is what ignited my interest; here’s a link to and a citation for it,

The Internet of Bodies—alive, connected and collective: the virtual physical future of our bodies and our senses by Ghislaine Boddington. AI Soc. 2021 Feb 8 : 1–17. DOI: 10.1007/s00146-020-01137-1 PMCID: PMC7868903 PMID: 33584018

Some excerpts from this open access paper,

The Weave—virtual physical presence design—blending processes for the future

Coming from a performing arts background, dance led, in 1989, I became obsessed with the idea that there must be a way for us to be able to create and collaborate in our groups, across time and space, whenever we were not able to be together physically. The focus of my work, as a director, curator and presenter across the last 30 years, has been on our physical bodies and our data selves and how they have, through the extended use of our bodies into digitally created environments, started to merge and converge, shifting our relationship and understanding of our identity and our selfhood.

One of the key methodologies that I have been using since the mid-1990s is inter-authored group creation, a process we called The Weave (Boddington 2013a, b). It uses the simple and universal metaphor of braiding, plaiting or weaving three strands of action and intent, these three strands being:

1. The live body—whether that of the performer, the participant, or the public;

2. The technologies of today—our tools of virtually physical reflection;

3. The content—the theme in exploration.

As with a braid or a plait, the three strands must be weaved simultaneously. What is key to this weave is that in any co-creation between the body and technology, the technology cannot work without the body; hence, there will always be virtual/physical blending. [emphasis mine]

Cyborgs

Cyborg culture is also moving forward at a pace with most countries having four or five cyborgs who have reached out into media status. Manel Munoz is the weather man as such, fascinated and affected by cyclones and anticyclones, his back of the head implant sent vibrations to different sides of his head linked to weather changes around him.

Neil Harbisson from Northern Ireland calls himself a trans-species rather than a cyborg, because his implant is permanently fused into the crown of his head. He is the first trans-species/cyborg to have his passport photo accepted as he exists with his fixed antenna. Neil has, from birth, an eye condition called greyscale, which means he only sees the world in grey and white. He uses his antennae camera to detect colour, and it sends a vibration with a different frequency for each colour viewed. He is learning what colours are within his viewpoint at any given time through the vibrations in his head, a synaesthetic method of transference of one sense for another. Moon Ribas, a Spanish choreographer and a dancer, had two implants placed into the top of her feet, set to sense seismic activity as it occurs worldwide. When a small earthquake occurs somewhere, she received small vibrations; a bigger eruption gives her body a more intense vibration. She dances as she receives and reacts to these transferred data. She feels a need to be closer to our earth, a part of nature (Harbisson et al. 2018).

Medical, non medical and sub-dermal implants

Medical implants, embedded into the body or subdermally (nearer the surface), have rapidly advanced in the last 30 years with extensive use of cardiac pacemakers, hip implants, implantable drug pumps and cochlear implants helping partial deaf people to hear.

Deep body and subdermal implants can be personalised to your own needs. They can be set to transmit chosen aspects of your body data outwards, but they also can receive and control data in return. There are about 200 medical implants in use today. Some are complex, like deep brain stimulation for motor neurone disease, and others we are more familiar with, for example, pacemakers. Most medical implants are not digitally linked to the outside world at present, but this is in rapid evolution.

Kevin Warwick, a pioneer in this area, has interconnected himself and his partner with implants for joint use of their personal and home computer systems through their BrainGate (Warwick 2008) implant, an interface between the nervous system and the technology. They are connected bodies. He works onwards with his experiments to feel the shape of distant objects and heat through fingertip implants.

‘Smart’ implants into the brain for deep brain stimulation are in use and in rapid advancement. The ethics of these developments is under constant debate in 2020 and will be onwards, as is proved by the mass coverage of the Neuralink, Elon Musk’s innovation which connects to the brain via wires, with the initial aim to cure human diseases such as dementia, depression and insomnia and onwards plans for potential treatment of paraplegia (Musk 2016).

Given how many times I’ve featured art/sci (also know as, art/science and/or sciart) and cyborgs and medical implants here, my excitement was a given.

Finally, here’s one of my earliest pieces about cyborgs titled ‘My mother is a cyborg‘ from April 20, 2012 and my September 17, 2020 posting titled, ‘Turning brain-controlled wireless electronic prostheses into reality plus some ethical points‘. If you scroll down to the ‘Brain-computer interfaces, symbiosis, and ethical issues’ subhead, you’ll find some article excerpts about a fascinating qualitative study on implants and ethics.

BrainGate demonstrates a high-bandwidth wireless brain-computer interface (BCI)

I wrote about some brain computer interface (BCI) work out of Stanford University (California, US), in a Sept. 17, 2020 posting (Turning brain-controlled wireless electronic prostheses into reality plus some ethical points), which may have contributed to what is now the first demonstration of a wireless brain-computer interface for people with tetraplegia (also known as quadriplegia).

From an April 1, 2021 news item on ScienceDaily,

In an important step toward a fully implantable intracortical brain-computer interface system, BrainGate researchers demonstrated human use of a wireless transmitter capable of delivering high-bandwidth neural signals.

Brain-computer interfaces (BCIs) are an emerging assistive technology, enabling people with paralysis to type on computer screens or manipulate robotic prostheses just by thinking about moving their own bodies. For years, investigational BCIs used in clinical trials have required cables to connect the sensing array in the brain to computers that decode the signals and use them to drive external devices.

Now, for the first time, BrainGate clinical trial participants with tetraplegia have demonstrated use of an intracortical wireless BCI with an external wireless transmitter. The system is capable of transmitting brain signals at single-neuron resolution and in full broadband fidelity without physically tethering the user to a decoding system. The traditional cables are replaced by a small transmitter about 2 inches in its largest dimension and weighing a little over 1.5 ounces. The unit sits on top of a user’s head and connects to an electrode array within the brain’s motor cortex using the same port used by wired systems.

For a study published in IEEE Transactions on Biomedical Engineering, two clinical trial participants with paralysis used the BrainGate system with a wireless transmitter to point, click and type on a standard tablet computer. The study showed that the wireless system transmitted signals with virtually the same fidelity as wired systems, and participants achieved similar point-and-click accuracy and typing speeds.

A March 31, 2021 Brown University news release (also on EurekAlert but published April 1, 2021), which originated the news item, provides more detail,

“We’ve demonstrated that this wireless system is functionally equivalent to the wired systems that have been the gold standard in BCI performance for years,” said John Simeral, an assistant professor of engineering (research) at Brown University, a member of the BrainGate research consortium and the study’s lead author. “The signals are recorded and transmitted with appropriately similar fidelity, which means we can use the same decoding algorithms we used with wired equipment. The only difference is that people no longer need to be physically tethered to our equipment, which opens up new possibilities in terms of how the system can be used.”

The researchers say the study represents an early but important step toward a major objective in BCI research: a fully implantable intracortical system that aids in restoring independence for people who have lost the ability to move. While wireless devices with lower bandwidth have been reported previously, this is the first device to transmit the full spectrum of signals recorded by an intracortical sensor. That high-broadband wireless signal enables clinical research and basic human neuroscience that is much more difficult to perform with wired BCIs.

The new study demonstrated some of those new possibilities. The trial participants — a 35-year-old man and a 63-year-old man, both paralyzed by spinal cord injuries — were able to use the system in their homes, as opposed to the lab setting where most BCI research takes place. Unencumbered by cables, the participants were able to use the BCI continuously for up to 24 hours, giving the researchers long-duration data including while participants slept.

“We want to understand how neural signals evolve over time,” said Leigh Hochberg, an engineering professor at Brown, a researcher at Brown’s Carney Institute for Brain Science and leader of the BrainGate clinical trial. “With this system, we’re able to look at brain activity, at home, over long periods in a way that was nearly impossible before. This will help us to design decoding algorithms that provide for the seamless, intuitive, reliable restoration of communication and mobility for people with paralysis.”

The device used in the study was first developed at Brown in the lab of Arto Nurmikko, a professor in Brown’s School of Engineering. Dubbed the Brown Wireless Device (BWD), it was designed to transmit high-fidelity signals while drawing minimal power. In the current study, two devices used together recorded neural signals at 48 megabits per second from 200 electrodes with a battery life of over 36 hours.

While the BWD has been used successfully for several years in basic neuroscience research, additional testing and regulatory permission were required prior to using the system in the BrainGate trial. Nurmikko says the step to human use marks a key moment in the development of BCI technology.

“I am privileged to be part of a team pushing the frontiers of brain-machine interfaces for human use,” Nurmikko said. “Importantly, the wireless technology described in our paper has helped us to gain crucial insight for the road ahead in pursuit of next generation of neurotechnologies, such as fully implanted high-density wireless electronic interfaces for the brain.”

The new study marks another significant advance by researchers with the BrainGate consortium, an interdisciplinary group of researchers from Brown, Stanford and Case Western Reserve universities, as well as the Providence Veterans Affairs Medical Center and Massachusetts General Hospital. In 2012, the team published landmark research in which clinical trial participants were able, for the first time, to operate multidimensional robotic prosthetics using a BCI. That work has been followed by a steady stream of refinements to the system, as well as new clinical breakthroughs that have enabled people to type on computers, use tablet apps and even move their own paralyzed limbs.

“The evolution of intracortical BCIs from requiring a wire cable to instead using a miniature wireless transmitter is a major step toward functional use of fully implanted, high-performance neural interfaces,” said study co-author Sharlene Flesher, who was a postdoctoral fellow at Stanford and is now a hardware engineer at Apple. “As the field heads toward reducing transmitted bandwidth while preserving the accuracy of assistive device control, this study may be one of few that captures the full breadth of cortical signals for extended periods of time, including during practical BCI use.”

The new wireless technology is already paying dividends in unexpected ways, the researchers say. Because participants are able to use the wireless device in their homes without a technician on hand to maintain the wired connection, the BrainGate team has been able to continue their work during the COVID-19 pandemic.

“In March 2020, it became clear that we would not be able to visit our research participants’ homes,” said Hochberg, who is also a critical care neurologist at Massachusetts General Hospital and director of the V.A. Rehabilitation Research and Development Center for Neurorestoration and Neurotechnology. “But by training caregivers how to establish the wireless connection, a trial participant was able to use the BCI without members of our team physically being there. So not only were we able to continue our research, this technology allowed us to continue with the full bandwidth and fidelity that we had before.”

Simeral noted that, “Multiple companies have wonderfully entered the BCI field, and some have already demonstrated human use of low-bandwidth wireless systems, including some that are fully implanted. In this report, we’re excited to have used a high-bandwidth wireless system that advances the scientific and clinical capabilities for future systems.”

Brown has a licensing agreement with Blackrock Microsystems to make the device available to neuroscience researchers around the world. The BrainGate team plans to continue to use the device in ongoing clinical trials.
