This study evaluates MR-guided focused ultrasound targeting the nucleus accumbens to reduce fentanyl motivation in rats, finding no significant effect despite confirming NAc as the target.

This study identifies distinct population coding patterns in the anterior insular cortex of sign- and goal-tracking rats during reward epochs, despite equivalent conditioned responding.

This study shows that CB1R signaling in the dorsomedial striatum affects Pavlovian outcome devaluation and inhibitory synaptic transmission, with sex differences observed in these effects.

This study shows that the psychedelic DOI increases dopamine signaling to reward cues but not distal cues, supporting error-driven learning mechanisms.

This study shows that reducing CB1R signaling in the VTA decreases sign-tracking behavior and alters cue-outcome dopamine dynamics in the NAc of rats.

This study examines dopamine signaling in the dorsal bed nucleus of the stria terminalis during Pavlovian learning and reward violations, revealing strategy-dependent patterns of dopamine responses.

The paper shows that inhibiting the BLA to aIC pathway makes sign-tracking rats sensitive to outcome devaluation while leaving goal-tracking rats unaffected, highlighting individual differences in Pavlovian behavior.

This study shows that BLA-NAc projections differentially affect flexibility in sign- and goal-tracking rats during outcome devaluation.
