This study characterizes molecular changes in the ventral striatum of individuals with cocaine use disorder using multi-omics and single-cell approaches, identifying perturbations in metabolic pathways and cell-type-specific alterations.

This study shows that alcohol-dependent rats show increased habitual behavior towards a sweet reward in two tasks, and DMS inactivation in non-dependent rats also increases habitual behavior.

This study shows that adolescent restraint stress in rats leads to long-term spinal neuron sensitization, which is further enhanced by a mild-nociceptive input in adulthood.

This study shows that adolescent peer-rejection in rats leads to lasting sex-dependent changes in alcohol-seeking behavior, with females showing increased reinstatement and males decreased reinstatement.

This study identifies a common molecular mechanism involving mGluR2 dysfunction linking cognitive deficits and alcohol craving, and develops a biomarker for targeted interventions.
