VIP type neurons connect two brain regions involved in memory consolidation
Researchers have discovered a type of neuron that would coordinate the consolidation of memory In an article published today in Nature Communications, researchers from Université Laval and Oxford University report having discovered a new type of neuron in the mouse brain. These neurons connect two structures associated with memory and may coordinate the consolidation of…

Can’t sleep? Fruit flies and energy drinks offer new clues
Source: MUHC Newsroom Sleep is an essential behavioural state in animals ranging from invertebrates to humans. It is critical for immune function, stable metabolism, brain repair, learning and memory. Over the course of a lifetime, more than 30 per cent of people will experience a sleep disorder, which is associated with a number of diseases…

Immune cells cross-talk to prevent damage-driving inflammation following CNS injury
New research by Samuel David at McGill University provides new insight on the role of macrophages and resident microglia following injury to the central nervous system. Infiltrating monocyte-derived macrophages (MDMs) and resident microglia dominate at sites of central nervous system (CNS) injury. These cells have different origins – MDMs arise from the bone marrow throughout…

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…

BrainsCAN study discovers sound sensitivity differences between age groups
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.

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…

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…

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…

Genetic model offers elegant tool for testing Parkinson’s disease therapies
For the past decade, Parkinson’s disease researchers have relied on the experimental equivalent of using a sledgehammer to tune a guitar to test new therapies for the disease. This may be a reason clinical trials of promising neuroprotective drugs fail. But, in new research published today in Nature Parkinson’s Disease, researchers at the Djavad Mowafaghian Centre for…
