My research focuses on the neuroscience of human communication using multiple neuroimaging modalities and physiological techniques. Current research areas focus on the development and mechanisms of sensorimotor control for spoken language, sensorimotor dysfunctions associated with stuttering and other speech motor disorders, neuroplasticity and sensorimotor learning, bilingualism and the relationship between language and music. Dr. Gracco is the Director of the multidisciplinary Centre for Research on Brain, Language and Music at McGill.
