Aging

Decision making across the lifespan

Several of the neurochemical systems implicated in reward-motivated decision making are known to undergo major changes during development. Chief among these are the dopamine system and the endogenous opioid systems, which are each critical for important aspects of reward-motivated behavior. We are currently studying how age-related changes in the function of these neurochemical systems contribute to changes in the way goals are selected and pursued as we pass from adolescence to old age.
