A neuroscientist retires after 50 years – a profile of Leo Renaud
by Sarah Ferguson Sheets of paper in organized stacks cover Dr. Leo Renaud’s desk. The hallway outside his office at the Civic campus of The Ottawa Hospital is quiet. The late afternoon sunlight shines through the office window, illuminating flecks of dust in the air. “Is the sun in your eyes?” Renaud asks. “Don’t be

Rapid eye movement sleep: keystone of memory formation
For decades, scientists have fiercely debated whether rapid eye movement (REM) sleep – the phase where dreams appear – is directly involved in memory formation. Now, a study published in Science by researchers at the Douglas Mental Health University Institute (McGill University) and the University of Bern provides evidence that REM sleep does, indeed, play

Mechanisms underlying efficient coding of natural stimuli revealed
Maurice Chacron and his team at McGill University have discovered that sensory neurons can efficiently encode stimuli by ensuring that the neuron’s tuning function is matched to the statistics of the input found in the organism’s natural environment.

What makes the brain tick so fast?
New study sheds light on the workings of brain neurotransmitter receptors Surprisingly complex interactions between neurotransmitter receptors and other key proteins help explain the brain’s ability to process information with lightning speed, according to a new study. Scientists at McGill University, working with collaborators at the universities of Oxford and Liverpool, combined experimental techniques to

Location may be key to effectively controlling pain
Targeting the pain receptor at the cell’s nucleus has a major effect on its ability to transmit pain signals. In real estate, location is key. It now seems the same concept holds true when it comes to stopping pain. New research published in Nature Communications by a team of researchers led by McGill University’s Director of Anesthesia Research

Accidental finding leads to brain circuit development discovery
Researchers at the University of Ottawa Brain and Mind Research Institute have pinpointed a set of rules that govern how brain circuits develop during early life, offering clues into neurodevelopmental disorders such as autism and schizophrenia. Published in Neuron, one of the most influential journals in the field of neuroscience, their study shows how neuroplasticity

Vulnerability to depression linked to noradrenaline
First-ever connection between noradrenergic neurons and vulnerability to depression The team of Bruno Giros, a researcher at the Douglas Mental Health University Institute and professor of psychiatry at McGill University, reports the first-ever connection between noradrenergic neurons and vulnerability to depression. Published in the journal Nature Neuroscience, this breakthrough paves the way for new depression
