Dоpаmine neurоns in the ventrаl tegmentаl area (VTA) have been hypоthesized to mediate reward-related learning by signaling reward prediction errors. 1. What is the correlative evidence that led to this hypothesis? 2. What evidence supports a causal role for VTA dopamine neurons in reward learning specifically? Please be specific about the causal manipulation used and the behavioral outcomes that were tested. 3. What other roles for VTA dopamine neurons have either been ruled out, or supported by causal manipulations? Please pick one example and describe the experimental evidence for or against the role of dopamine neurons in the psychological or behavioral process that you picked.
