Idan Segev is the David & Inez Myers Professor in Computational Neuroscience and former director of the Interdisciplinary Center for Neural Computation (ICNC) at the Hebrew University of Jerusalem. His research team utilizes computational tools to study how neurons, the elementary microchips of the brain, compute and dynamically adapt to our ever-changing environment. The ultimate goal is to un- ravel how local fine variations within the cortical network underlie specific computations (e.g., the orientation of a bar in the visual system) and may give rise to certain brain diseases or to a healthy individual brain.
