報告簡介：One of the greatest challenges in modern science is to understand how the brain produces cognition and behavior. My research focuses on the elemental units of function in the cerebral cortex of nonhuman primates. Using neuroimaging methods in anesthetized and awake, trained monkeys, we have shown that these 200 um sized functional domains encode object features and are modulated by attention. Furthermore, these domains are selectively connected in functional networks that underly specific sensorimotor behaviors. We are now developing an optical brain-machine interface that permits both readout (via optical imaging and functional magnetic resonance imaging methods) and modulation of behavioral networks with selective stimulation (electrical microstimulation, pulsed laser stimulation, and optogenetics). These approaches are aimed at elucidating the circuitry underlying vision, touch, and selective attention. Such knowledge will lead to new understanding and treatment of neurological and mental disease.
