Cocaine use disorder (CUD) is a chronic neuropsychiatric condition characterized by a compulsion to use cocaine, resulting from enduring cellular and molecular adaptations. Among substance use disorders (SUDs), CUD is notable for its rising prevalence and the lack of approved pharmacotherapies. The nucleus accumbens (NAc), integral to the brain's reward circuitry, plays a crucial role in the initiation and continuation of maladaptive behaviors intrinsic to CUD. Leveraging advancements in neuroproteomics, we undertook an in-depth proteomic analysis of the NAc in a mouse model that spans membran

Addictions often develop in a social context, although the influence of social factors did not receive much attention in the neuroscience of addiction. Recent animal studies suggest that peer presence can reduce cocaine intake, an influence potentially mediated, among others, by the subthalamic nucleus (STN). However, there is to date no neurobiological study investigating this mediation in humans.This study investigated the impact of social context and drug cues on brain correlates of inhibitory control in individuals with and without cocaine use disorder (CUD) using functional Magnetic Reson
