This paper introduces a new model of learning in the basal ganglia that scales prediction errors by reward uncertainty, showing improved performance in noisy environments and alignment with physiological features.

The paper tests whether reward prediction errors (RPEs) influence risk-seeking behavior and finds that positive RPEs increase risk-seeking while negative RPEs increase risk-aversion.

The paper examines whether plasticity rules can extract payoffs and costs from reward prediction errors in basal ganglia pathways, showing they can infer action values with specific conditions.
