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

Leave a reply

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!

FaceBook event:

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
RSVP: Please RSVP at EventBrite (https://imaging-a-window-into-the-brain.eventbrite.ca) or email info@arpico.ca

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!

On the verge of controlling neurons by wireless?

Leave a reply

Scientists have controlled a mouse’s neurons with a wireless device (and unleashed some paranoid fantasies? well, mine if no one else’s) according to a July 16, 2015 news item on Nanowerk (Note: A link has been removed),

A study showed that scientists can wirelessly determine the path a mouse walks with a press of a button. Researchers at the Washington University School of Medicine, St. Louis, and University of Illinois, Urbana-Champaign, created a remote controlled, next-generation tissue implant that allows neuroscientists to inject drugs and shine lights on neurons deep inside the brains of mice. The revolutionary device is described online in the journal Cell (“Wireless Optofluidic Systems for Programmable In Vivo Pharmacology and Optogenetics”). Its development was partially funded by the [US] National Institutes of Health [NIH].

The researchers have made an image/illustration of the probe available,

A July 16, 2015 US NIH National Institute of Neurological Disorders and Stroke news release, which originated the news item, describes the study and notes that instructions for building the implant are included in the published study,

“It unplugs a world of possibilities for scientists to learn how brain circuits work in a more natural setting.” said Michael R. Bruchas, Ph.D., associate professor of anesthesiology and neurobiology at Washington University School of Medicine and a senior author of the study.

The Bruchas lab studies circuits that control a variety of disorders including stress, depression, addiction, and pain. Typically, scientists who study these circuits have to choose between injecting drugs through bulky metal tubes and delivering lights through fiber optic cables. Both options require surgery that can damage parts of the brain and introduce experimental conditions that hinder animals’ natural movements.

To address these issues, Jae-Woong Jeong, Ph.D., a bioengineer formerly at the University of Illinois at Urbana-Champaign, worked with Jordan G. McCall, Ph.D., a graduate student in the Bruchas lab, to construct a remote controlled, optofluidic implant. The device is made out of soft materials that are a tenth the diameter of a human hair and can simultaneously deliver drugs and lights.

“We used powerful nano-manufacturing strategies to fabricate an implant that lets us penetrate deep inside the brain with minimal damage,” said John A. Rogers, Ph.D., professor of materials science and engineering, University of Illinois at Urbana-Champaign and a senior author. “Ultra-miniaturized devices like this have tremendous potential for science and medicine.”

With a thickness of 80 micrometers and a width of 500 micrometers, the optofluidic implant is thinner than the metal tubes, or cannulas, scientists typically use to inject drugs. When the scientists compared the implant with a typical cannula they found that the implant damaged and displaced much less brain tissue.

The scientists tested the device’s drug delivery potential by surgically placing it into the brains of mice. In some experiments, they showed that they could precisely map circuits by using the implant to inject viruses that label cells with genetic dyes. In other experiments, they made mice walk in circles by injecting a drug that mimics morphine into the ventral tegmental area (VTA), a region that controls motivation and addiction.

The researchers also tested the device’s combined light and drug delivery potential when they made mice that have light-sensitive VTA neurons stay on one side of a cage by commanding the implant to shine laser pulses on the cells. The mice lost the preference when the scientists directed the device to simultaneously inject a drug that blocks neuronal communication. In all of the experiments, the mice were about three feet away from the command antenna.

“This is the kind of revolutionary tool development that neuroscientists need to map out brain circuit activity,” said James Gnadt, Ph.D., program director at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS).  “It’s in line with the goals of the NIH’s BRAIN Initiative.”

The researchers fabricated the implant using semi-conductor computer chip manufacturing techniques. It has room for up to four drugs and has four microscale inorganic light-emitting diodes. They installed an expandable material at the bottom of the drug reservoirs to control delivery. When the temperature on an electric heater beneath the reservoir rose then the bottom rapidly expanded and pushed the drug out into the brain.

“We tried at least 30 different prototypes before one finally worked,” said Dr. McCall.

“This was truly an interdisciplinary effort,” said Dr. Jeong, who is now an assistant professor of electrical, computer, and energy engineering at University of Colorado Boulder. “We tried to engineer the implant to meet some of neurosciences greatest unmet needs.”

In the study, the scientists provide detailed instructions for manufacturing the implant.

“A tool is only good if it’s used,” said Dr. Bruchas. “We believe an open, crowdsourcing approach to neuroscience is a great way to understand normal and healthy brain circuitry.”
