Professor of Neurology, Neurobiology & Anatomy, Ophthalmology and Brain and Cognitive Sciences
University of Rochester School of Medicine and Dentistry

Charles J. Duffy, MD is Professor of Neurology, Neurobiology & Anatomy, Ophthalmology and Brain and Cognitive Sciences. Dr. Duffy studies the neuronal and perceptual mechanisms of spatial orientation; how people know where they are and how they find their way through the visual environment. Single neuron recordings in monkey cerebral cortex are used to characterize responses to optic flow, the patterned visual motion that people see as a result of their own movements. His ongoing studies combine optic flow visual displays with real translational movement of the monkey using a room-sized, motorized sled. The human psychophysical studies are directed at analyzing the cortical operations involved in optic flow field perception. His current focus is on studies of perceptual involvement in the syndrome of visuospatial disorientation in Alzheimer's disease. He is the Assistant Editor of the journal Neurology. He is an active clinician, based at Monroe Community Hospital, where he interacts with current geriatric fellows on a daily basis.
