Striatal dopamine explains novelty-induced behavioral dynamics and individual variability in threat prediction

The paper uses machine learning to analyze novelty-induced behaviors and finds that dopamine in the striatum correlates with individual variability and is explained by a reinforcement learning model of threat prediction.

Distinct temporal difference error signals in dopamine axons in three regions of the striatum in a decision-making task

The paper shows dopamine axon activity in three striatal regions is similar but differs in reward response bias, which relates to habit and skill.
