The current focus of my research is to investigate the effects of stress and stimulants on brain neurochemistry and behavior. Our laboratory has demonstrated that rats exposed to unpredictable stress for ten days show altered neurotransmitter activity as measured through microdialysis with high performance liquid chromatography when challenged with a novel acute stressor or with stimulants. Current studies are aimed at elucidating the changes that account for the altered neurotransmitter release and the effects of the altered neurotransmitter release on neural circuits associated with rewarding and aversive experiences. We have begun to assess the long-term effects of childhood exposure to stimulants, such as methampetamines or Ritalin, on adult learning and other motivated behaviors.
