Contingency degradation overwrites initial learning and depends on lateral orbitofrontal cortex

The paper shows that non-contingent outcome delivery reduces responding in rats without recovery, and this effect depends on the lateral orbitofrontal cortex.

Disrupting astrocyte signalling in the nucleus accumbens impairs incentive-driven instrumental actions

This study shows that disrupting astrocyte signaling in the nucleus accumbens impairs instrumental actions driven by general arousal but not by specific outcome 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.

Hippocampal neuroinflammation causes sex-specific disruptions in action selection, food approach memories, and neuronal activation

High fat diet allows food-predictive stimuli to energize action performance in the absence of hunger, without distorting insulin signaling on accumbal cholinergic interneurons.
