Bendesky, Andrés

Assistant Professor of E3B in the Mortimer B. Zuckerman Mind Brain Behavior Institute

Research Description

There are profound differences in behavior among individuals of a species and across species. Much effort has been devoted to the observation and theory of behavioral variation, but the molecular, genetic, and neurobiological mechanisms that generate and maintain such diversity are largely unknown. My lab studies the mechanisms of behavioral variation from genetic and neurobiological angles – by identifying specific genes involved and how they impact the brain, and by characterizing functional variation in neuronal circuits. We then analyze the common themes that emerge to describe the evolution of behavior.
