My lab studies the neuronal circuitry and functional organization underlying visual and tactile behavior in awake, behaving monkeys. To map these functions in the brain, we use an array of optical imaging, fMRI, electrophysiological, anatomical and optogenetics methods. Chronic implanted windows on the brain permit: 1) study of sensory and attentional processes and 2) methods to influence brain activity with electrical, laser, and optogenetic stimulation methods. This combined behavioral, functional, anatomical, and neuroengineering approach will lead to development of future mind-machine interfaces that modify and enhance function in normal and diseased states.
