My lab studies the neural mechanisms that transform vision into action. We are specifically interested in how the brain encodes movement goals relative to the self and other visual landmarks, how these goals are updated during self-motion, and how they are transformed into commands for coordinated eye, head, and hand motion during reach.<\/p>\n\n\n\n
To study these questions, we use a variety of techniques, including computational modeling, psychophysical and behavioral measurements, neurophysiological recordings, neuroimaging, brain stimulation, and sometimes work with patient populations. We often collaborate with other York, Canadian, and international research labs. My students typically focus on one or two areas \/ techniques for their own experiments, conference presentations, and publications, and they often collaborate, exposing each other to a broad range of approaches to neuroscience.<\/p>\n\n\n\n
