Research focus
This article may help explain addiction science through research on alcohol, brain science, animal study. The source abstract begins by describing: “The transition to alcohol use disorder (AUD) involves persistent neuroadaptations in executive control functions primarily regulated by the medial prefrontal cortex.”
Key finding: In conclusion alterations in PL synaptic activity were strongly associated with individual addiction scores, indicating their role as potential markers of the behavioral manifestations linked to AUD psychopathology.
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 opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “The mechanisms contributing to alcohol use disorder (AUD) are complex and the orexigenic peptide ghrelin, which enhances alcohol reward, is implied as a crucial modulator.”
Key finding: Collectively, our data show that DAG attenuates alcohol-related responses in rodents, an effect opposite to that of ghrelin, and contributes towards a deeper insight into behaviors regulated by the ghrelinergic signaling pathway.

This article may help explain addiction science through research on opioid, alcohol, dopamine, brain science. The source abstract begins by describing: “Opioid-alcohol polysubstance use is prevalent and worsens treatment outcomes.”
Key finding: Thus, alcohol alters the motivation to seek oxycodone in a sex-dependent manner and the neural circuitry engaged by cue-primed reinstatement of sucrose and oxycodone-seeking.

This article may help explain addiction science through research on alcohol, brain science, withdrawal, mental health. The source abstract begins by describing: “Binge drinking is a significant problem in adolescent populations, and because of the reciprocal interactions between ethanol (EtOH) consumption and the endocannabinoid (eCB) system, we sought to determine if adolescent EtOH intake altered the localization…”
Key finding: These findings indicate that repeated exposure to EtOH during adolescence leads to long-term deficits in CB1 receptor expression, eCB-eLTD, and reduced recognition memory, but that these functional deficits can be restored by treatments that increase endogenous 2-arachidonoylglycerol.

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.
