This study reveals spatially organized dopamine dynamics in the nucleus accumbens core of mice, showing distinct patterns in anterior and posterior regions that do not align with canonical reward prediction error models.

This paper shows that presenting outcomes without cues (retrospective extinction) can erase memories, unlike standard extinction protocols that present cues without outcomes.

The paper shows that the rate of behavioral and dopaminergic learning in mice is proportional to the reward interval, with a model explaining this relationship.

The paper investigates neuronal assembly sequences in the mouse orbitofrontal cortex during learning, finding pre-existing and emergent sequences involved in memory consolidation and retrieval.

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

This study investigates the role of VIP neurons in mouse medial prefrontal cortex during reversal learning, finding they are critical for rapid behavioral adjustments but not for incremental learning.

This study shows that mesostriatal dopamine responses change when specific cue-reward contingencies are altered, suggesting dopamine encodes event relationships during learning.

The paper identifies cortical neuron ensembles that couple differently to hippocampal SWRs in distinct subregions and proposes their role in cognitive map formation.

This study identifies distinct roles of IT and PT neurons in working memory and temporal processing during a delayed response task in mice.
