Dr. Brodie has studied the effects of acute and chronic alcohol on neurons of the ventral tegmental area (VTA) for many years, and his work has helped elucidate how alcohol acts to increase dopamine neurotransmission in the brain. In conjunction with the CARE, Dr. Brodie is interested in examining epigenetic factors in the VTA that are altered by chronic alcohol exposure and produce sustained changes in the physiology of the VTA during withdrawal. The goal of this work is to understand the neurobiological basis of alcohol effects on the reward and reinforcement systems of the brain.

Title Description Investigator(s) Category Status
Epigenetic mechanisms of positive affective state of alcoholism This component will examine novel epigenetic mechanisms (HDAC-induced chromatin remodeling) that may be involved in changes in the putative DA neurons’ response to γ-aminobutyric acid (GABA) after chronic ethanol exposure and its withdrawal.
