Striatal D2-neurons gate D1-mediated associative encoding under uncertainty

The paper identifies D2-SPNs as transiently recruited during early learning to regulate D1-SPN dopamine signaling and improve action-outcome encoding under uncertainty.

Towards the definition and measurement of routines and the cognitive processes that underpin their maintenance

This paper defines and measures routines using transition entropy, showing that routine maintenance is disrupted by frequent task switches and altered reward expectations.

Dorsomedial striatal neuroinflammation causes excessive goal-directed action control by disrupting astrocyte function

The paper shows that striatal neuroinflammation disrupts astrocyte function, leading to excessive goal-directed action control in rats.

Striatal dopamine encodes the relationship between actions and reward

This study investigates how striatal dopamine encodes action-outcome relationships in rats, finding that dopamine release becomes lateralized to reflect the strength of these associations.

Evidence against the detectability of a hippocampal place code using functional magnetic resonance imaging

This paper shows that a hippocampal place code cannot be detected using fMRI in a controlled virtual navigation experiment.
