Serotonergic Fibers as Random Walks-A Spatial Analysis

Environmental reward-predictive stimuli provide a major source of motivation for adaptive reward-seeking behaviors, which can become amplified in the addicted state, allowing cues to become potent 'triggers' for maladaptive behavior (e.g., drug seeking). I will present recent data from our lab showing that phasic dopamine signaling in the nucleus accumbens core tracks this cue-motivated behavior and that cue-evoked NAc dopamine responses are sensitive to need state, one critical variable that determines the current adaptive utility of such behavior.

To make adaptive decisions we must cast ourselves into the future and consider the possible outcomes of our potential choices. This prospective consideration is informed by our memories. I will discuss our lab’s recent work investigating the neural circuits responsible for encoding, updating, and retrieving reward memories for use in the considerations underlying decision making. We have taken a multifaceted approach to these investigations, combining modern circuit dissection and behavioral tools.
