Dr. Schwendt is interested in what causes drug addiction to be a chronic relapsing disorder. He is interested in identifying cellular and molecular mechanisms underlying relapse and drug-induced cognitive deficits which persist well into abstinence. His research utilizes an animal model with high-face validity for human addiction: operant drug self-administration in combination with tasks designed to test memory performance in animals. In particular, his research attempts to elucidate the role of modulatory proteins that ‘fine-tune’ synaptic transmission during development of drug-induced neural plasticity, and further, to investigate whether in vivo manipulation of these proteins can attenuate or reverse drug-seeking and drug-induced cognitive deficits. Dr. Schwendt believes that characterization of the molecular underpinnings of the long-lasting behavioral consequences of repeated drug administration will provide critical insight into the psychopathology of drug addiction and related psychiatric disorders (including schizophrenia and depression).
