Education 1981, B.Sc. Honors, University of Sussex, Brighton, England Research InterestThe basic research program in our laboratory focuses on dysfunction of cortico-limbic-striatal circuits that may subserve increased impulsivity and alterations in reward-related learning that have relevance to drug addiction (Jentsch & Taylor 1999, Psychopharmacology, 146:373-390 ) as well as other psychiatric disorders such as depression, schizophrenia, ADHD and Tourette Syndrome. Our current studies are examining how DA-regulated intracellular signaling molecules and alterations in associated neurotrophin molecules within the prefrontal cortex, amygdala and accumbens contributes to associative aspects of incentive motivation, learning and memory function. Our studies in monkeys have also found long-lasting deficits in inhibitory control after repeated cocaine exposure and alterations in reward-related learning. In addition, we examine sex differences in attention, motivation, and impulse control in rats, as well as sex differences in aspects of cocaine self-administration and underlying molecular alterations. We examine several addictive/abused drugs such as cocaine, amphetamine, PCP, THC, MDMA, nicotine and alcohol. Ongoing studies use genetically manipulated mouse models, intra-cerebral infusion techniques, and viral-vector mediated overexpression of targeted genes in combination with sophisticated behavioral assessment techniques in mice, rats and monkeys.
