In light of the revelation about the mishandling of Miami Dolphins quarterback Tua Tagovailoa’s concussion, conversations about the role of concussions in many sports, especially youth hockey, have been reinvigorated. Dr. Charles Tator, a prominent Canadian neurosurgeon, Order of Canada recipient, and director of the Canadian Concussion Centre (CCC) at[Read More…]

Exercise in a pill for those with rare movement disorders
Spinocerebellar ataxia type 6 (SCA6), a rare neurodegenerative disorder, is characterized by severe, progressive movement and balance issues. It is associated with low levels of a neural molecule called brain-derived neurotrophic factor (BDNF), which guides the growth and maintenance of brain cells and overall plasticity. SCA6 affects one in 100,000[Read More…]
Honey, I shrunk the brains!
Aging is one of the few truly universal experiences, yet it is one of those things that no one really looks forward to. Along with visible signs like wrinkles and grey hair, however, comes a more insidious and harder-to-combat symptom: The decline of brain function. But according to a new[Read More…]
Mapping behaviour using genetic biomarkers
What if you could visibly lay out your entire genome sequence in front of you and see almost everything that explains who you are, from your eye colour to whether you’re an introvert or an extrovert? If this were true, we look at someone’s genes and calculate whether they will[Read More…]
Mapping concussion symptoms in the brain
Concussions affect more than 200,000 Canadians each year, but, despite the injury’s prevalence, patients with the same symptoms often respond to the same treatment differently. This is why some children and adolescents who suffer concussions recover in a few weeks, while others may suffer symptoms lasting several months or even[Read More…]
Neuroinflammation found to drive Alzheimer’s disease progression
Over a century ago, Alois Alzheimer, a German psychiatrist, spotted strange plaques and tangles in the brain slides of a patient with dementia. Ever since, scientists have been trying to better understand the mechanisms behind what is now known as Alzheimer’s disease. Alzheimer’s disease (AD) is a brain disorder that[Read More…]
How the brain and body synchronize to keep a beat
People often say that practice makes perfect, and music is no exception. From virtuosos to amateurs, rehearsal is a key part of mastering the craft. A recent study led by Caroline Palmer, a professor in McGill’s Department of Psychology, questioned if practice truly does make perfect, or if underlying genetic[Read More…]
The brain in higher resolution
McGill’s new 7T Magnetic Resonance Imaging (MRI) machine, located at the Montreal Neurological Institute (MNI) or ‘the Neuro,’ is the first of its kind in Canada. The T refers to ‘Tesla’, the unit of measurement for the magnetic strength of the machine. At 7T, it outperforms the 3T MRI machine[Read More…]
A brain without a body
Parkinson’s disease affects the dopamine neurons in as many as ten million people worldwide yet, to this day, nobody has identified a concrete cause. However, science may be a step closer, as researchers have recently shown that the protein alpha synuclein detrimentally affects the brains of Parkinson’s patients. Scientists have[Read More…]
Questioning the device we use to question
To kickoff the Science Undergraduate Society’s ‘Academia Week: To Science and Beyond,’ David Ragsdale, associate professor in the Department of Neurology and Neurosurgery, explored questions on morality and neuroscience. Within every human head, there is a tangible organ associated with something fundamentally intangible: The mind. “Your brain is a physical[Read More…]
