Aggression can be intrinsically rewarding and is shaped by specific brain circuits. This study identifies an orexin-sensitive inhibitory microcircuit in the lateral habenula that promotes aggression and its rewarding properties. ... Read More

Heroin-conditioned cues selectively enhance dMSN and dopamine activity while inhibiting iMSNs in the nucleus accumbens. These pathway-specific dynamics drive reward learning. ... Read More

Dopamine release is suppressed when rewards are the expected outcome of self-initiated actions. These signals reveal sequence-specific prediction errors during goal-directed behavior. ... Read More
