This study shows that mesolimbic dopamine ramps occur only when inter-trial intervals are short relative to trial periods during conditioning.

The paper shows that cholinergic pauses and dopamine reward prediction errors differ across striatal subregions in rats during decision-making tasks.

The paper shows that blue light can falsely trigger dopamine release measurements using RdLight1, questioning previous findings on cholinergic interneurons' role in dopamine release.

This study shows that D1+ neurons in the nucleus accumbens fire more during reward expectation and trial initiation, while D2+ neurons respond more to reward delivery.

This study shows that cholinergic interneurons in the nucleus accumbens drive dopamine release, influencing motivated behavior in rats.

The paper shows dopamine signals in different striatal regions encode reward prediction errors over distinct time scales, supporting adaptive learning across behaviors.

This study investigates the role of the medial prefrontal cortex in guiding orienting behavior in rats, finding lateralized and time-dependent effects of PFC inactivation on decision-making.

The paper shows that dopamine release in forebrain regions correlates with reward expectation, while VTA dopamine cell firing shows error-like responses, suggesting distinct mechanisms for motivation signals.
