The purpose of my NSERC-funded program of research is to determine how spinal reflex circuits integrate input from the brain and peripheral sensory receptors to maintain optimal voluntary drive to muscle during fatigue. I am also interested in the inhibitory pathways that modulate the excitability of the primary motor cortex during fatigue. This research is significant because until we understand the central mechanisms that modulate muscle output in healthy people, we cannot fully understand the mechanisms of impaired motor function in injury, aging, and disease.
