Research Interests
I use electrophysiological and imaging
methods to study the dynamics of population of neurons in the primary
visual cortex. The questions I have addressed aim at understanding how
neurons respond over time to features of the visual stimulus on a
millisecond time scale. Traditionally, such questions have been
addressed at the single cell level. My approach instead is to
simultaneously record the activity of large populations of neurons.
Specifically, I have been studying the selectivity of neurons for
orientation: oriented stimuli elicit wave-like activity in the visual
cortex and I have characterized such responses through a combination of
recording methods (multi-array recording, politrodes, voltage sensitive
dye imaging, intrinsic imaging) and modeling approaches as well. I am
particularly interested in understanding how such activity affects the
correlation between responses of neurons and how it interacts with the
natural ongoing dynamics of the cortex.
