Orbitofrontal circuits for context-gated reward predictions

This study investigates how orbitofrontal cortex circuits regulate reward predictions in different contexts using optogenetics and computational modeling in rats.

Partially dissociable roles of the Orbitofrontal cortex and dorsal Hippocampus in context-dependent (hierarchical) reward predictions and contextual inference in learning

This study investigates the roles of the orbitofrontal cortex and dorsal hippocampus in context-dependent hierarchical reward predictions and learning using chemogenetic inactivations in rats.

Sex differences in discrimination behavior and orbitofrontal engagement during context-gated reward prediction

This study examines sex differences in contextual control over reward prediction in rats, finding females show slower acquisition but more robust performance with increased orbitofrontal cortex activation.
