This study investigates how VTA dopamine neuron activity shapes stimulus and action value representations in the striatum through conditioned reinforcement in mice.

The paper introduces a feature-specific reward prediction error model to explain heterogeneity in dopamine neuron responses in the VTA and shows it aligns with neural recordings.

This paper introduces a theory of hippocampal replay that explains how replay builds a cognitive map for navigation, reconciling conflicting hypotheses about its function and predicting new experimental outcomes.
