Research Areas:

ageing, connectivity, corticospinal neurons, motor performance & learning, neuroimaging, neurophysiology, stroke, post COVID-19 condition

Current research: 

Prof. Boudrias' main focus of research aims to understand the neurophysiological mechanisms underlying the interaction between brain areas in ageing subjects and stroke patients. She uses multimodal functional neuroimaging and electrophysiological techniques as well as state-of-the-art data analysis methods to measure the precise dynamics of these interactions. The general aim of her research is to identify robust and sensitive biomarkers of motor ability and in the longer term, to design subject-specific therapeutic interventions such as physical training or stimulation protocols to maintain motor function and/or alleviate age-related declines in motor performance. She is also interested in assessing the impact of the COVID19 pandemic on the brain and on the delivery of rehabilitation services in COVID-designated rehabilitation centers in Quebec.
