This study investigates whether negative affective states persist in rats after oxycodone self-administration and abstinence, finding no significant differences in negative affect tests compared to saline controls.

This study uses calcium and dopamine sensors to examine nucleus accumbens activity during food seeking and extinction-reinstatement paradigms, finding changes in both signals during training and reinstatement.

This study shows that cocaine exposure increases calreticulin in the ventral hippocampus via ΔFosB, reducing excitability in the vHPC-NAc circuit and promoting cocaine seeking and reward.

This study investigates the role of dopamine transmission at D1 and D2 receptors in the nucleus accumbens in incubated cocaine craving, finding that DA contributes to craving after incubation through postsynaptic changes.
