Zayd M. Khaliq, Ph.D. is a joint faculty member at the National Institute on Drug Abuse (NIDA) and the National Institute of Neurological Disorders and Stroke (NINDS), where he is chief of the Cellular Neurophysiology Section. His research focuses on dopamine-releasing neurons located in the midbrain, which play an essential role in movement and reward-based behaviors. Dysfunction of these neurons has been linked to a variety of brain disorders including addiction, schizophrenia, depression and Parkinson’s disease. The goal of our research is to understand 1) how voltage-gated ion channels contribute to excitability and action potential firing of dopamine neurons and other neurons that participate in reward circuits, 2) how synaptic inputs interact with intrinsic membrane conductances to produce spiking patterns that are relevant to reward-based learning, 3) and how neuromodulatory inputs influence excitability of these neurons. We address these questions using patch-clamp techniques to record the activity of neurons in brain slices. We combine this approach with imaging, immunohistochemistry and the use of transgenic mice to identify specific populations of neurons within the reward circuit.
