Illustration by Jeremy Leung, Published 14:37, May. 19, 2021 In the ’90s, when he was a doctoral student at the University of Lausanne, in Switzerland, neuroscientist Sean Hill spent five years studying how cat brains respond to noise. At the time, researchers knew that two regions the cerebral cortex, which is the outer layer of the brain, and the thalamus, a nut-like structure near the centre did most of the work. But, when an auditory signal entered the brain through the ear, what happened, specifically? Which parts of the cortex and thalamus did the signal travel to? And in what order? The answers to such questions could help doctors treat hearing loss in humans. So, to learn more, Hill, along with his supervisor and a group of lab techs, anaesthetized cats and inserted electrodes into their brains to monitor what happened when the animals were exposed to sounds, which were piped into their ears via miniature headphones. Hill’s probe then captured the brain s ....
E-Mail TORONTO - Scientists at the Krembil Brain Institute, part of University Health Network (UHN), in collaboration with colleagues at the Centre for Addiction and Mental Health (CAMH), have used precious and rare access to live human cortical tissue to identify functionally important features that make human neurons unique. This experimental work is among the first of its kind on live human neurons and one of the largest studies of the diversity of human cortical pyramidal cells to date. The goal of this study was to understand what makes human brain cells human, and how human neuron circuitry functions as it does, says Dr. Taufik Valiante, neurosurgeon, scientist at the Krembil Brain Institute at UHN and co-senior author on the paper. ....
If you could upload your mind into a computer, would you? How AI is making science fiction real In a new documentary, A.rtificial I.mmortality filmmaker Ann Shin explores whether AI can make us live forever and what that would mean Author of the article: Chris Knight Publishing date: Apr 28, 2021 • 16 hours ago • 6 minute read • Ann Shin (at right) poses with Erica, robot creation of Hiroshi Ishiguru.
