Neural basis of visual processing

Our lab investigates the neural basis of visual shape representation and recognition. Our focus is area V4, an intermediate stage in the shape processing pathway in primates.

We use a combination of single-cell neurophysiology experiments, behavioral manipulations and computational modeling to address questions about how visual stimuli are represented in the brain, how these representations arise and how they ultimately underlie behavior.
