Biography
Eyal Seidemann received his Ph.D. in Neuroscience from Stanford University. He studies the cortical mechanisms that mediate visual perception and visually guided behavior. In his own words: the central goal of my research is to understand how perceptual decisions and motor plans are represented and processed in the primate cerebral cortex. To address this general question, we employ a powerful combination of imaging, genetic and electrophysiological techniques in awake, behaving primates. Our ability to measure and manipulate neural responses in the cortex of alert animals puts us in a unique position; it allows us to directly visualize and perturb cortical activity in real-time, while subjects perform demanding perceptual or motor tasks. We then build computational models that attempt to explain how the measured neural activity could lead to the observed behavior. Finally, we test the predictions of these quantitative models by measuring how perceptual judgments or motor plans change following selective manipulations of the neural response using optogenetic, electrical or pharmacological techniques.
