Research focus
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.
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 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, 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 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, dopamine, brain science, withdrawal. The source abstract begins by describing: “The anterior cingulate cortex (ACC) is implicated in many pathologies, including depression, anxiety, substance-use disorders, and pain.”
Key finding: This commonality potentially suggests that the ACC is a locus for multiple withdrawal symptoms.

This article may help explain addiction science through research on opioid, cocaine, methamphetamine, dopamine. The source abstract begins by describing: “Methamphetamine (METH) is a widely abused psychostimulant, whose hyper-rewarding property is believed to underlie its addictive effect, but the molecular mechanism regulating this effect remains unclear.”
Key finding: Our findings demonstrate an important role for NAc novel-m009C in regulating METH reward, reveal a novel molecular regulator of the actions of METH on brain reward circuitries and provide a new strategy for treating METH addiction based on the modulation of small non-coding RNAs.
