Professor Emeritus (Retired)
The research in the Visual Neuroscience laboratory follows from the long-standing traditions of sensory physiology and psychophysics, with the ultimate goal of understanding sensation and perception. We are investigating the visual system in monkeys, cats, and humans. We want to understand the neurophysiology of the visual system and how it relates to visual perception. To that end, we perform single-neuron electrophysiological experiments: we measure the electrical activity of individual neurons located in the visual cortex of monkeys and cats while systematically varying visual stimuli. These measurements are then quantitatively evaluated within the context of specific theoretical and formal mathematical/computational models.
