Research Abstract

The goal of our lab is to define how neurons from different cortical areas interact to realize our perception of shape and motion. We study this question in the brain of the rhesus macaque, recording action potentials from neurons that span the entire cortico-visual hierarchy, from V1, V2, V4, MT and inferotemporal cortex (IT). We believe that the best explanation for visual processing is mathematical – thus we work to ensure that all of our results can be implemented in computational models like deep neural networks. read more
