Effects of PPP1R1B (DARPP-32) Polymorphism on Feedback-related Brain Potentials across the Life Span

Effects of PPP1R1B (DARPP-32) Polymorphism on Feedback-related Brain Potentials across the Life Span

Maximizing gains during probabilistic reinforcement learning requires the updating of choice–outcome expectations at the time when the feedback about a specific choice or action is given. Extant theories and evidence suggest that dopaminergic modulation plays a crucial role in reinforcement learning...
