Individual members of the Canadian Association for Neuroscience (CAN) have alerted us to the fact that a number of scientists across Canada are being denied visas to enter the United States to attend the next annual Society for Neuroscience meeting in San Diego. Many are students and postdoctoral fellows who have left their home countries to dedicate their energy and talents to research into devastating brain and mental health conditions that afflict millions worldwide. CAN takes the position that the exchange of ideas cannot be limited by political boundaries. To do so severely compromises the ability of the scientific enterprise to develop new ideas and advance humanity. Scientists must have the ability to travel freely to discuss their work and interact with colleagues across the globe.
New research by Chin-An Wang and Douglas Munoz, at Queen’s University, shows that a brain region called the intermediate superior colliculus (SCi) helps regulate the size of the pupil to optimize visual sensitivity and sharpness. Interestingly, brain processing of an object begins even before one shifts their gaze towards the object. This research shows that the size of the pupil is adjusted to the light level of the target, independent of the general light level, before the movement of the eyes towards this target.
Congratulations to the new fellows of the Canadian Academy of Health Sciences. Induction into the CAHS as a Fellow is considered one of the highest honours within Canada’s academic community.
The newly inducted fellows include the following neuroscientists:
Neuroscientists from Western University have discovered a difference in the way younger and older adults respond to sounds. In the BrainsCAN study, researchers found that the brain becomes more sensitive to sounds as a person ages, which likely causes hearing challenges over a lifetime.
Researchers say the findings provide a convincing reason to keep concussed athletes on the bench even if they no longer exhibit any symptoms.
Detailed scans of concussed University of British Columbia hockey players found that the protective fatty tissue surrounding brain cell fibres was loosened two weeks after the injury—even though the athletes felt fine and were deemed ready to return to the ice.
When it comes to weight gain, the problem may be mostly in our heads, and our genes
Clinicians should consider how the way we think can make us vulnerable to obesity, and how obesity is genetically intertwined with brain structure and mental performance, according to new research.
The study, led by researchers at the Montreal Neurological Institute and Hospital (The Neuro) and published in the Proceedings of the National Academy of Sciences on Aug. 28, 2018, was an examination of magnetic resonance imaging (MRI) and cognitive test data from 1,200 individuals, supplied as part of the Human Connectome Project.
The Royal Society of Canada has recently announced new Fellows in the Academies of Arts and Humanities, Social Sciences, and Science. They have been elected by their peers for their outstanding scholarly, scientific and artistic achievement. Recognition by the RSC is the highest honour an individual can achieve in the Arts, Social Sciences and Sciences.
The RSC also welcomed new Members of the College of New Scholars, Artists and Scientists, that include top mid-career leaders in Canada. The College provides the RSC with a multigenerational capacity to help Canada and the world address major challenges and seize new opportunities including those identified in emerging fields.
