Older adult concussion research

Dr. Brian Christie (Division of Medical Sciences; Institute on Aging & Lifelong Health (IALH)) and Dr. Jodie Gawryluk (Psychology, cross-appointed Division of Medical Sciences; IALH acting director) will collaborate with researchers at Université de Montréal and NeuroTracker on an innovative concussion research project that aims to better understand the long-term consequences of, and potential treatments for, mild traumatic brain injuries in older adults.

Dark microglia and extracellular matrix remodelling

Microglia, the brain’s resident immune cells, play a key role in remodelling the brain, which helps regulate synaptic plasticity – the ability for brain connections to change, which is fundamental to learning and memory – and behaviour throughout a person’s lifetime. Now, Dr. Marie-Ève Tremblay and her students are trying to figure out if dark microglia, a stressed form of the cells, perform this remodelling process and lead to changes in behaviour and synaptic plasticity in the context of chronic stress.
