“Patterned microstimulation as proof of concept for prosthetic 3D motion vision”Our lab studies how neural activity gives rise to complex perceptual and cognitive functions. Our goal is to expand the neurobiology of decision making into the more natural regime of multiple, time-varying streams of evidence, in both unisensory (visual motion) and multisensory conditions (visual and vestibular signals for self-motion). We are developing new stimuli and task variants to probe the spatial and temporal factors influencing perceptual judgments, and to elucidate the neural representation and readout of sensory uncertainty. In addition to providing basic mechanistic insight, the combination of sophisticated behavior with multi-site neural recording and stimulation could inform the development of cortical prosthetics targeting impaired vision and spatial orientation.
