Synaptic plasticity of the Reward Pathway

Since the discovery of synaptic plasticity as the cellular correlate of learning and memory, strong overlaps between neural and cellular substrates of learning, drug addiction and stress-related disorders have been recognized. Yet it remains a major challenge to identify the neural circuits and synaptic mechanisms contributing to abnormalities in dopamine signaling induced by addictive drugs and adverse early life experiences. The major focus of my laboratory is the elucidation of synaptic mechanisms underlying reward learning, drug addiction and neuropsychiatric disorders such as depression, with particular emphasis on the midbrain dopamine system originating from the ventral tegmental area (VTA) and its control by the lateral habenula (LHb). Research in our laboratory also explores effects of severe early life stress on synaptic transmission and plasticity of distinct VTA dopamine circuits to identify the neural circuits and molecular mechanisms contributing to abnormalities in dopamine signaling induced by adverse early life experiences. To achieve these goals, we use a combination of immunohistochemical, biochemical, epigenetic, electrophysiological and behavioral techniques. We expect that identifying novel epigenetic mechanisms in the regulation of synaptic plasticity and memory formation in midbrain dopamine circuits will point to new directions in pharmacotherapy for drug addiction and stress-related disorders.
