Eyal Seidemann received his undergraduate and Master's degrees from Tel Aviv University in Israel. Dr. Seidemann conducted his graduate studies at Stanford University and obtained his PhD in Neuroscience in 1998. He then pursued his postdoctoral work with Amiram Grinvald at the Weizmann Institute of Science in Israel, where he was the first recipient of the Koshland Scholarship. Dr. Seidemann joined the faculty at the University of Texas at Austin in the Fall of 2002. He is currently an Associate Professor of Psychology and Neurobiology and a member of the Center for Perceptual Systems and the Institute for Neuroscience.

Research Summary:

The central goal of my research is to understand how perceptual events and motor plans are represented and processed in the primate cerebral cortex. To address these questions, we employ a novel combination of optical imaging and electrophysiological techniques in awake, behaving primates. Our ability to record optically from the cortex of alert animals puts us in a unique position; it allows us to directly visualize 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 electrical microstimulation or pharmacological microinjections.
