Cortical circuits and neuronal mechanisms of visual perception
My research involves the investigation of circuits for encoding and decoding visual attributes and how this impacts perception and action in monkeys and humans. There are three related areas in this research program. We study the anatomical circuits that underlie different visual pathways using connectomic approaches. We use confocal imaging and focused-ion-beam/scanning electron microscopy to identify different neuron types and synaptic structure in visual circuits. In complementary studies in monkeys we investigate the functional properties of different neuron types or clusters to determine how they are involved in encoding. Single cell recording is made with single and multi-electrode techniques to allow the determination of the multidimensional receptive field properties of visually responsive neurons. Thirdly, we use the information from these two approaches to generate models of populations of cortical neurons that seek to understand the principles of how the circuits operate.
I work in close collaboration with other NYU investigators including Bob Shapley and Tony Movshon.
