Identification of a brain region involved in controlling pupil dilatation to optimize vision

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. 

Concussions loosen insulation around brain cells

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.

The link between obesity, the brain, and genetics

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.

Congratulations to newly elected fellows of the Royal Society of Canada, and to the incoming class of the college of new scientists

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.
