Varsity athletes face hundreds of head impacts each season, some big enough to cause a concussion, others so small they barely register. But science is suggesting that even these quiet hits that don't cause concussions may quietly reshape the brain. In this episode, we dive into the neuroscience of concussive and subconcussive impacts. We unpack what science is revealing about how the athlete brain changes and what this means for the future of sport, safety, and long-term brain health.

Coljae Berry is a second-year MSc student in the Centre for Neuroscience Studies at Queen's University, working under the supervision of Dr. Cook. In collaboration with the Queen's Varsity Football Team, his research investigates how repeated non-concussive impacts affect white matter microstructure and sensorimotor function in collegiate football players. He hopes to raise awareness for player safety and educate the public about the potential risks and long-term effects of playing football. Outside of his research, Coljae is passionate about rehabilitation for neurodegenerative diseases and traumatic brain injuries. He is also an active advocate for Black student voices on campus.
