We are interested in understanding how the sensory world
is represented in the mammalian brain. Individual neurons
in sensory areas are selectively responsive to specific aspects
of world - neurons in the visual cortex, for example, prefer
certain orientations of edges and respond to specific spacing
of dark and bright regions. The process by which neuronal
responses become selective is constrained by both genetically
determined events and by the environment to which a young
animal is exposed. How these selective response properties
develop, become organized within a sensory area, and how
this organization contributes to the perception of the world
are the focus of my research. Our current research goals
are to understand how information about spatial and temporal
components of a scene is encoded in the primary visual cortex.
We are studying the functional organization of the visual
cortex in both normal animals and in an animal model of the
cortical visual pathology known as amblyopia.
