Revealed that ventral tegmental area dopamine (VTA DA) projects to the basolateral amygdala (BLA). Dopamine is released in the BLA during stimulus-reward pairing. Necessary and sufficient for associating identifying reward features with predictive cues, but does not assign general incentive properties to cues or mediate reinforcement. Dopamine's contribution to learning has long been known. These learning signals have conventionally been interpreted as caching general reward values in predictors and reinforcing corresponding policies that rely on past success rather than prospectively considering specific outcomes4,5,6. Adaptive decision-making, however, often requires such prospective consideration. To ensure flexible behavior, humans and other animals not only learn predictive events' general values but also encode relations between these cues and identifying features of their associated outcomes. Little is known about its function because it receives less attention than more common VTA DA projections to the nucleus accumbens and prefrontal cortex. BLA itself has recently been shown important in forming detailed identity-specific cue–reward memories. Dopamine is released in the BLA during stimulus-reward learning. Nor does it assign general incentive properties to cues to support nonspecific motivation. These data reveal that the VTA DA →BLA pathway contributes importantly to forming detailed, identity-specific cue–reward memories, fundamental components of internal models of environmental relationships (also known as cognitive maps) that support flexible decision-making. #neuroscience
