Research Focus

The Zorrilla laboratory seeks to understand the neural substrates of motivated behavior and of the regulatory control of energy balance using interdisciplinary molecular, biochemical, neuroanatomical, pharmacological, physiological, behavioral and statistical techniques. We are particularly interested in genetic, epigenetic and neuroadaptive differences in the neurobiology of reward and stress circuits that subserve the control of food intake as well as of other appetitive (reward-driven) and stress-related behaviors. Our work aims to be therapeutically relevant to the increased incidence of obesity, binge eating disorders, alcoholism and drug addiction, and stress-related psychiatric disorders of anxiety and depression in industrialized societies.
