Keith McGregor is an Assistant Professor in the Department of Neurology and a VA Merit Scientist. Dr. McGregor is the Director of the Transcranial Stimulation Lab at the VA Center for Visual and Neurocognitive Rehabilitation (CVNR) and Director of Telerehabilitation. His current projects employ multimodal imaging and neurophysiological techniques (TMS, tDCS, fMRI and DTI) to investigate brain function. Dr. McGregor's work has shown that aging is associated with decreased levels of cortical inhibition, which affects motor control including motor learning. A major facet of this aging related phenomenon, however, is that individual differences in physical activity level appear to mitigate changes in cortical communication. Dr. McGregor's research has shown that lifestyle interventions can lessen or even reverse aging-related declines in behavioral performance in motor and cognitive domains. These findings have great relevance to rehabilitation programs which may be augmented by the incorporation of increased levels of physical activity and exogenous brain stimulation.  

Dr. McGregor received his PhD from the University of Florida in 2010 in Cognitive and Behavioral Neuroscience and completed his undergraduate studies at the College of the Holy Cross in 1997.
