In an ever-changing environment, animals must be constantly learning new actions. When a new action-outcome is formed, the learned association is dependent on the expected value of the reinforcer. Various works in diverse species has confirmed the role of the Dorsomedial Striatum (DMS) in learning and performing goal-directed actions. But where in the brain is the expected value being updated? The Basolateral Amygdala (BLA), which project broadly to DMS, has previously been implicated in tracking the value of specific stimuli associated with learning. I wish to understand the role of BLA and its DMS projections in signaling the expected value of action outcomes, and associating changes in value with learning of novel, goal-directed actions.
