Research focus
This article may help explain addiction science through research on alcohol, brain science, genetics, animal study. The source abstract begins by describing: “Alcohol use disorder (AUD) is characterized by compulsive drinking, which is thought to be mediated by effects of chronic intermittent ethanol exposure on the dorsal striatum, the input nucleus of the basal ganglia.”
Key finding: These data provide important clues as to the impact of ethanol on striatal biology and provide a key resource for future investigation.
Why this may help: This may help explain why addiction can involve brain, behavior, mental health, craving, relapse, or treatment factors rather than simple willpower alone. It should be read as research information, not personal medical advice.
This article may help explain addiction science through research on opioid, alcohol, nicotine, brain science. The source abstract begins by describing: “Preclinical and human studies indicate psilocybin may reduce perseverant maladaptive behaviors, including nicotine and alcohol seeking.”
Key finding: We conclude that psilocybin reduces heroin relapse and highlight IL-17a signaling as a potential downstream pathway of psilocybin that also reduces heroin seeking.

This article may help explain addiction science through research on alcohol, brain science, genetics, mental health. The source abstract begins by describing: “Somatostatin (SST) neurons have been implicated in a variety of neuropsychiatric disorders such as depression and anxiety, but their role in substance use disorders, including alcohol use disorder (AUD), is not fully characterized.”
Key finding: Together these data revealed an SST-mediated microcircuit in the PL that modulates the inhibitory dynamics of pyramidal neurons, a major source of output to subcortical targets to drive reward-seeking behaviors and emotional response.

This article may help explain addiction science through research on alcohol, brain science, genetics, mental health. The source abstract begins by describing: “Genome wide association and animal studies have implicated genetic variations in CHRNΑ5, encoding the α5 subunit-containing nicotinic acetylcholine receptors (α5*nAChRs), as a risk factor for developing alcohol use disorders (AUDs).”
Key finding: IPN GABAergic neurons expressing α5*nAChRs play a key role in limiting both EtOH drinking and motor impulsivity.

This article may help explain addiction science through research on alcohol, cannabis, brain science, withdrawal. The source abstract begins by describing: “Alcohol use disorder (AUD) remains a pervasive public health issue with limited effective treatments.”
Key finding: These findings indicate that chronic CBD administration attenuates both behavioral and neurobiological facets of alcohol dependence by modulating neuronal excitability and preventing neurodegeneration, supporting its therapeutic potential for AUD and providing mechanistic insights for future research.

This article may help explain addiction science through research on cocaine, dopamine, brain science, craving. The source abstract begins by describing: “The authors show that rostral ventral pallidum projections to the ventral tegmental area (VTA) are activated during cue-induced reinstatement of cocaine seeking, and DREADD inhibition of these projections blocks this behavior.”
Key finding: This double dissociation in ventral pallidum subregional roles in drug seeking is likely to be important for understanding the mesocorticolimbic circuits underlying reward seeking and addiction.
