Striatal Gradient in Value-Decay Explains Regional Differences in Dopamine Patterns and Reinforcement Learning Computations

2025-01-24

Abstract excerpt

Dopamine has been suggested to encode reward-prediction-error (RPE) in reinforcement learning (RL) theory, but also shown to exhibit heterogeneous patterns depending on regions and conditions: some exhibiting ramping response to predictable reward while others only responding to reward-predicting cue. It remains elusive how these heterogeneities relate to various RL algorithms proposed to be employed by animals/hu...
