Emergence in Toronto and Ottawa and brains in Vancouver (Canada): three April 2018 events

April 2018 is shaping up to be quite the month where art/sci events are concerned. I just published a March 27, 2018 posting titled ‘Curiosity collides with the quantum and with the Science Writers and Communicators of Canada in Vancouver (Canada)‘ and I’ve now received news about more happenings in Toronto and Ottawa.  Plus, there’s a science-themed meeting organized by ARPICO (Society of Italian Researchers &; Professionals in Western Canada) featuring brains and brain imaging in Vancouver.

Toronto’s and Ottawa’s Emergence

There’s an art/sci exhibit opening, from a March 27, 2018 Art/Sci Salon announcement (received via email),

You are invited!

The Oakwood Village Library and Arts Centre event:

341 Oakwood Avenue, Toronto, ON  M6E 2W1

I check the library webpage listed in the above and found this artist’s statement,

Artist / Scientist Statement [Stephen Morris]

I am interested in self-organized, emergent patterns and textures. I make images of patterns both from the natural world and of experiments in my laboratory in the Department of Physics at the University of Toronto. Patterns naturally attract casual attention but are also the subject of serious scientific research. Some things just evolve all by themselves into strikingly regular shapes and textures. Why? These shapes emerge spontaneously from a dynamic process of growing, folding, cracking, wrinkling, branching, flowing and other kinds of morphological development. My photos are informed by the scientific aesthetic of nonlinear physics, and celebrate the subtle interplay of order and complexity in emergent patterns. They are a kind of “Scientific Folk Art” of the science of Emergence.

While the official opening is April 5, 2018, the event itself runs from April 1 – 30, 2018.

Next, there’s another March 27, 2018 announcement (received via email) from the Art/Sci Salon but this one concerns a series of talks about ’emergence’, Note: Some of the event information was a little difficult to decipher so I’ve added a note to the relevant section).

What is Emergent Form?

Nature teems with self-organized forms that seem to spring spontaneously from the smooth background of things, by mechanisms that are not always apparent. Think of rippled sand on a beach or regular stripes in the clouds.  Plants, insects and animals exhibit spirals and spots and stripes in an exuberant riot of colours.  Fluid flows in amazingly regular swirls and eddies.  The emergence of form is ubiquitous, and presents a challenge and an inspiration to both artists and scientists. In mathematics, patterns appear as solutions of the nonlinear partial differential equations in the continuum limit of classical physics, chemistry and biology. In the arts and humanities, “emergent form” addresses the entangled ways in which humans, plants animals, microorganisms inevitably co-exist in the universe; the way that human intervention and natural transformation can generate new landscapes and new forms of life.

With Emergent Form, we want to question the idea of a fixed world.

For us, Emergent Form is not just a series of natural and human phenomena too complicated to understand, measure or predict, but also a concept to help us identify ways in which we can come to term with, and embrace their complexity as a source of inspiration.

Join us in Toronto and Ottawa for a series of interdisciplinary discussions, performances and exhibitions on Emergent Form on Apr 10, 11, 12 (Toronto) and Apr. 14 [2018] (Ottawa).

This series is the result of a collaboration among several parties. Each event of the series is different and has its dedicated RSVP

Imaging: A Window into the Brain

Brain illness, comprising neurological disorders, mental illness and addiction, is considered the major health challenge in the 21st century with a socio-economic cost greater than cancer and cardiovascular disease combined. There are at least three unique challenges hampering brain disease management: relative inaccessibility, disease onset often preceding the onset of clinical symptoms by many years and overlap between clinical and pathological symptoms that makes accurate disease identification often difficult. This talk will give examples of how positron emission tomography (PET) imaging has contributed to better understanding of the brain function and disease with particular focus on Parkinson’s disease. Emphasis will be placed on the interplay between scientific discoveries and instrumentation and data analysis development as exemplified by the current understanding of the brain function as comprised by interactions between connectivity networks and neurochemistry and advancement in multi-modal imaging such as simultaneous PET and magnetic resonance imaging (MRI).

Vesna Sossi is a Professor in the University of British Columbia (UBC) Physics and Astronomy Department and at the UBC Djavad Mowafaghian Center for Brain Health. She directs the UBC Positron Emission Tomography (PET) imaging centre, which is known for its use of imaging as applied to neurodegeneration with emphasis on Parkinson’s disease. Her main areas of interest comprise development of imaging methods to enhance the investigation of neurochemical mechanisms that lead to an increased risk of Parkinson’s disease (PD) and mechanisms that contribute to treatment-related complications. She uses PET imaging to explore how alterations of the different neurotransmitter systems contribute to different trajectories of disease progression. Her other areas of interest are PET image analysis, instrumentation and multi-modal, multi-parameter data analysis. She published more than 180 peer review papers, is funded by several granting agencies, including the Michael J Fox Foundation, and sits on several national and international review panels.


WHEN: Wednesday, April 11th, 2018 at 7:00pm (doors open at 6:45pm)
WHERE: Roundhouse Community Centre, Room B – 181 Roundhouse Mews, Vancouver, BC, V6Z 2W3

Tickets are Needed

  • Tickets are FREE, but all individuals are requested to obtain “free-admission” tickets on EventBrite site due to limited seating at the venue. Organizers need accurate registration numbers to manage wait lists and prepare name tags.
  • All ARPICO events are 100% staffed by volunteer organizers and helpers, however, room rental, stationery, and guest refreshments are costs incurred and underwritten by members of ARPICO. Therefore to be fair, all audience participants are asked to donate to the best of their ability at the door or via EventBrite to “help” defray costs of the event.

I have one idle question. What’s going to happen these groups if Canadians change their use of  Facebook or abandon the platform as they are threatening to do in the face of Cambridge Analytica’s use of their data? A March 25, 2018 article on huffingtonpost.ca outlines the latest about Canadians’ reaction to the Cambridge Analytical news according to an Angus Reid poll,

A survey by Angus Reid Institute suggests 73 per cent of Canadian Facebook users say they will make changes, while 27 per cent say it will be “business as usual.”

Nearly a quarter (23 per cent) said they would use Facebook less in the future, and 41 per cent of users said they would check and/or change their privacy settings.

The survey also found that one in 10 say they plan to abandon the platform, at least temporarily.

Facebook has been under fire for its ability to protect user privacy after Cambridge Analytica was accused of lifting the Facebook profiles of more than 50 million users without their permission.

There you have it.

*Well, a bit more information about one of the “Emergent’ speakers was received in an April 4, 2018 ArtSci Salon email announcement,

Do make sure to check out Pier Luigi Capucci’s EU-based (but with international breadth) Noemalab platform. https://noemalab.eu/ since the mid-nineties, this platform has been an important node of information for New Media Art and the relation between the arts and science.

noemalab’s blog regularly hosts reviews of events and conferences occurring around the world, including  the Subtle Technologies Festival between 2007 and 2014. you can search its archives here http://blogs.noemalab.eu/

Capucci has been writing several reflections on emergent forms of Life and theorized what he called the “third life”. See a recent essay https://noemalab.eu/memo/events/evolutionary-creativity-the-inner-life-and-meaning-of-art/ here is a picture which I would love him to explain during Emergent Form. Intrigued? come listen to him!

What is a multiregional brain-on-a-chip?

In response to having created a multiregional brain-on-a-chip, there’s an explanation from the team at Harvard University (which answers my question) in a Jan. 13, 2017 Harvard John A. Paulson School of Engineering and Applied Sciences news release (also on EurekAlert) by Leah Burrows,

Harvard University researchers have developed a multiregional brain-on-a-chip that models the connectivity between three distinct regions of the brain. The in vitro model was used to extensively characterize the differences between neurons from different regions of the brain and to mimic the system’s connectivity.

“The brain is so much more than individual neurons,” said Ben Maoz, co-first author of the paper and postdoctoral fellow in the Disease Biophysics Group in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). “It’s about the different types of cells and the connectivity between different regions of the brain. When modeling the brain, you need to be able to recapitulate that connectivity because there are many different diseases that attack those connections.”

“Roughly twenty-six percent of the US healthcare budget is spent on neurological and psychiatric disorders,” said Kit Parker, the Tarr Family Professor of Bioengineering and Applied Physics Building at SEAS and Core Faculty Member of the Wyss Institute for Biologically Inspired Engineering at Harvard University. “Tools to support the development of therapeutics to alleviate the suffering of these patients is not only the human thing to do, it is the best means of reducing this cost.”

Researchers from the Disease Biophysics Group at SEAS and the Wyss Institute modeled three regions of the brain most affected by schizophrenia — the amygdala, hippocampus and prefrontal cortex.

They began by characterizing the cell composition, protein expression, metabolism, and electrical activity of neurons from each region in vitro.

“It’s no surprise that neurons in distinct regions of the brain are different but it is surprising just how different they are,” said Stephanie Dauth, co-first author of the paper and former postdoctoral fellow in the Disease Biophysics Group. “We found that the cell-type ratio, the metabolism, the protein expression and the electrical activity all differ between regions in vitro. This shows that it does make a difference which brain region’s neurons you’re working with.”

Next, the team looked at how these neurons change when they’re communicating with one another. To do that, they cultured cells from each region independently and then let the cells establish connections via guided pathways embedded in the chip.

The researchers then measured cell composition and electrical activity again and found that the cells dramatically changed when they were in contact with neurons from different regions.

“When the cells are communicating with other regions, the cellular composition of the culture changes, the electrophysiology changes, all these inherent properties of the neurons change,” said Maoz. “This shows how important it is to implement different brain regions into in vitro models, especially when studying how neurological diseases impact connected regions of the brain.”

To demonstrate the chip’s efficacy in modeling disease, the team doped different regions of the brain with the drug Phencyclidine hydrochloride — commonly known as PCP — which simulates schizophrenia. The brain-on-a-chip allowed the researchers for the first time to look at both the drug’s impact on the individual regions as well as its downstream effect on the interconnected regions in vitro.

The brain-on-a-chip could be useful for studying any number of neurological and psychiatric diseases, including drug addiction, post traumatic stress disorder, and traumatic brain injury.

“To date, the Connectome project has not recognized all of the networks in the brain,” said Parker. “In our studies, we are showing that the extracellular matrix network is an important part of distinguishing different brain regions and that, subsequently, physiological and pathophysiological processes in these brain regions are unique. This advance will not only enable the development of therapeutics, but fundamental insights as to how we think, feel, and survive.”

Better neuroprostheses for brain diseases and mental illneses

I don’t often get news releases from Sweden but I do on occasion and, sometimes, they even come in their original Swedish versions. In this case, Lund University sent me an English language version about their latest work making brain implants (neural prostheses) safer and effective. From a Sept. 29, 2015 Lund University news release (also on EurekAlert),

Neurons thrive and grow in a new type of nanowire material developed by researchers in Nanophysics and Ophthalmology at Lund University in Sweden. In time, the results might improve both neural and retinal implants, and reduce the risk of them losing their effectiveness over time, which is currently a problem

By implanting electrodes in the brain tissue one can stimulate or capture signals from different areas of the brain. These types of brain implants, or neuro-prostheses as they are sometimes called, are used to treat Parkinson’s disease and other neurological diseases.

They are currently being tested in other areas, such as depression, severe cases of autism, obsessive-compulsive disorders and paralysis. Another research track is to determine whether retinal implants are able to replace light-sensitive cells that die in cases of Retinitis Pigmentosa and other eye diseases.

However, there are severe drawbacks associated with today’s implants. One problem is that the body interprets the implants as foreign objects, resulting in an encapsulation of the electrode, which in turn leads to loss of signal.

One of the researchers explains the approach adopted by the research team (from the news release),

“Our nanowire structure prevents the cells that usually encapsulate the electrodes – glial cells – from doing so”, says Christelle Prinz, researcher in Nanophysics at Lund University in Sweden, who developed this technique together with Maria Thereza Perez, a researcher in Ophthalmology.

“I was very pleasantly surprised by these results. In previous in-vitro experiments, the glial cells usually attach strongly to the electrodes”, she says.

To avoid this, the researchers have developed a small substrate where regions of super thin nanowires are combined with flat regions. While neurons grow and extend processes on the nanowires, the glial cells primarily occupy the flat regions in between.

“The different types of cells continue to interact. This is necessary for the neurons to survive because the glial cells provide them with important molecules.”

So far, tests have only been done with cultured cells (in vitro) but hopefully they will soon be able to continue with experiments in vivo.

The substrate is made from the semiconductor material gallium phosphide where each outgrowing nanowire has a diameter of only 80 nanometres (billionths of a metre).
