Abstrakt: Dopamine (DA) responses are synonymous with the 'reward prediction error' of reinforcement learning (RL), and are thought to update neural estimates of expected value. A recent study by Dabney et al. enriches this picture, demonstrating that DA neurons track variability in rewards, providing a readout of risk in the brain.
