We study neural mechanisms of visual-motor integration and the neural basis of cognition (e.g. attention). We study the activity of single neurons in visual and motor structures within the brain, examine how perturbing that activity affects neurons in other brain structures, and also how it affects the perceptual and motor performance of behaving animals. Questions currently addressed by our group include: (1) How are the signals conveyed by visual cortical neurons used to guide eye movements? (2) How does oculomotor feedback affect processing in visual cortex? (3) What is the impact of planned movements on visual perception? (4) What are the neural circuits and neural computations that control selective attention? Our laboratory is also driven to develop more powerful approaches to systems-level neurobiological questions.
