Research in the Vaughn Lab

We investigate the endogenous cannabinoid (marijuana-like) system. The brain makes its own endogenous cannabinoids which interact with cannabinoid receptors to cause effects on a number of physiological systems including anxiety and mood, control of food intake, learning and memory, reward and addiction, stress, analgesia and temperature regulation. We are particularly interested in three aspects of cannabinoid physiology: the role of endocannabinoids in stress-induced relapse to cocaine seeking behavior, the role of endocannabinoids in anxiety, and the role of endocannabinoids in analgesia.
