Psychiatry Decision-Making & Reward Research
Scientists in NYU Langone’s Department of Psychiatry conduct groundbreaking decision-making and reward research. An interdisciplinary team, led by Paul W. Glimcher, PhD, uses different technologies to study decision-making in a range of environments.
Psychiatrists, psychologists, economists, and basic neuroscientists collaborate in the Glimcher Lab to assess decision-making, impulsivity, and the performance of new behavioral tasks in patients with opioid addiction.
They also study behavior in healthy populations using questionnaires, clinical survey work, and competitive and strategic economic games. Studying groups of people allows the team to understand how decision-making evolves in social settings.
The researchers use functional MRI (fMRI) and PET scans in humans to evaluate brain function and study how networks of neurons aggregate in decision-making. We collaborate with researchers at NYU Neuroscience to assess these same measures in animal models.
Another component of our work is digital health research. We use mobile applications to measure clinical and real-world behaviors and decision-making in healthy populations and those with addiction.
Much of our clinical research is focused on the development of tools to help physicians monitor the effectiveness of treatment for opioid dependence, contend with relapse, and evaluate patients’ clinical status.
Neuroeconomic Investigation of Craving in Opioid Addiction
We are evaluating brain function in patients at NYC Health + Hospitals/Bellevue using fMRI brain scans at the beginning and end of six months of treatment for opioid use disorder. Researchers are also investigating patients’ impulsivity and risk-taking behaviors throughout the study period. Our goals are to determine how treatment improves these behaviors, and to assess changes in neurobiology. View additional clinical trial details.
Basic and Translational Research
We conduct both basic and translational research. For example, our research team has developed tools in the laboratory for measuring risk attitude and impulsivity and used fMRI in animal models to evaluate the neurobiological basis of these behaviors. Our scientists have also conducted landmark studies using fMRI to elucidate the role of dopamine in addiction and decision-making.
Ongoing projects include the following.
Neural Mechanisms of Cost and Benefit Integration During Decision-Making
Scientists are conducting a series of fMRI assessments in humans as well as single-unit recording and muscimol inactivation experiments in monkeys to evaluate the neural activity involved in weighing costs and benefits during decision-making. The goal is to test whether separate anterior areas of the brain maintain different representations of costs and benefits.
Adaptation in Decision Circuits: Temporal History and the Efficiency of Choice
Researchers are using electrophysiological recording, computational modeling, and choice behavior experiments in humans and animals to assess how the brain represents subjective value and how these representations adapt over time. This study may one day have implications in depression and bipolar disorder, illnesses that are characterized by periods of low- and high-reward states.
Our research is funded by the National Institutes of Health.
