This study identifies distinct neural circuits for encoding and retrieving predictive learning in decision-making, showing the BLA-IL-NAc-S circuit is required for retrieval while BLA-NAc-S is only needed for encoding.

This study shows that silencing cholinergic input from the basal forebrain to the infralimbic cortex during fear extinction prevents fear renewal, highlighting nicotinic signaling as a therapeutic target.

This study shows that infralimbic cortex inhibitory memories are flexible, as they can be retrieved and used across different inhibitory procedures and contexts.

This study investigates the role of D1 and D2 neurons in the nucleus accumbens shell in stimulus-based decision-making using optogenetics in rats.

The paper shows that thalamostriatal degeneration impairs goal-directed behavior in rats, but this deficit can be reversed by enhancing striatal cholinergic activity with selegiline.

This study investigates the roles of direct and indirect pathway neurons in the posterior dorsomedial striatum in goal-directed learning and response flexibility.
