Professional Interests
My lab investigates how visual information is encoded and processed by populations of cortical neurons, and how this processing is affected by recent stimulus history, or adaptation. Our work thus addresses issues of neural coding, cortical plasticity, corticocortical signaling, and the neuronal basis of visual perception. Our approach involves multielectrode recordings in early and midlevel visual areas of anesthetized and awake, behaving macaque monkeys as well as in the visual aeas of the mouse. We use computational methods to interpret and understand physiological data, and psychophysical methods to relate our findings to human perception.
