This study shows that noradrenergic signaling in the orbitofrontal cortex adjusts learning rates based on environmental volatility, improving adaptive decision-making in rats.

This study shows that mPFC noradrenergic transmission is critical for updating stimulus-outcome associations after contingency degradation, while vlOFC is not involved.

This study shows that an obesogenic diet during adolescence impairs specific memory types via overactivation of hippocampal pathways, and targeting these pathways can reverse deficits.

This study shows that noradrenergic projections to the rodent orbitofrontal cortex are necessary for updating action-outcome relationships during reversal learning.

This study uses chemogenetic inhibition to show that periadolescent obesogenic diet affects hippocampus and amygdala memory functions differently, impairing hippocampus-dependent memory and enhancing amygdala-dependent memory.

This study shows that dopamine modulates the exploration-exploitation trade-off in rats by increasing exploration when dopaminergic activity is reduced.
