The paper identifies miR-10a-5p as a molecular regulator of impulsivity in the nucleus accumbens, linking it to dopaminergic signaling and impulsive-compulsive disorders.

This study identifies transcriptomic changes in rat habenula and amygdala after chronic fentanyl self-administration, linking them to human cell types and risk genes for addiction.

In 14 rats doing probabilistic reversal learning, model-derived uncertainty (unsigned average prediction error) and recency-weighted reward history distinctly and sex-specifically shaped win-stay versus lose-shift choices.

This study shows that sequence termination cues, via dopamine signaling, drive habitual behavior by enhancing automaticity and reducing behavioral flexibility.

This study shows that mesostriatal dopamine responses change when specific cue-reward contingencies are altered, suggesting dopamine encodes event relationships during learning.

This study shows chronic ethanol exposure impairs cognitive flexibility and striatal decision signals in male rats, with specific changes in neural representations of actions and outcomes.

This study shows pramipexole reduces impulsivity in highly impulsive rats by modulating frontostriatal networks, specifically through Zif268 mRNA downregulation in the nucleus accumbens core.

This study compares the effects of unilateral and bilateral subthalamic nucleus deep brain stimulation on apathy, depression, and anxiety in Parkinson's disease using pre-clinical and clinical approaches.
