Research focus
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.
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, 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.

This article may help explain addiction science through research on opioid, dopamine, brain science, withdrawal. The source abstract begins by describing: “μ-opioid receptor (MOR) was previously shown to be necessary for opiate reward, analgesia and dependence.”
Key finding: Our study demonstrates that a subpopulation of striatal direct-pathway neurons is sufficient to support opiate reward-driven behaviors and provides a new intersectional genetic approach to dissecting neurocircuit-specific gene function in vivo.

This article may help explain addiction science through research on opioid, cocaine, dopamine, brain science. The source abstract begins by describing: “Persistent transcriptional events in ventral tegmental area (VTA) and other reward relevant brain regions contribute to enduring behavioral adaptations that characterize substance use disorder.”
Key finding: These findings establish an essential role for H3Q5dop, and its downstream transcriptional consequences, in heroin-induced functional plasticity in VTA.

This article may help explain addiction science through research on opioid, brain science, withdrawal, relapse. The source abstract begins by describing: “Opioid use disorder (OUD) is a chronic relapsing disorder that is a major burden for the lives of affected individuals, and society as a whole.”
Key finding: Altogether, these animal models will contribute to study behavioural and neuronal circuitries involved in the several negative affective signs characterizing OUD.

This article may help explain addiction science through research on opioid, cocaine, methamphetamine, dopamine. The source abstract begins by describing: “Substance use disorder (SUD) represents a substantial challenge in neuropsychiatric medicine, with the molecular mechanisms underlying its etiology remaining elusive.”
Key finding: Our findings highlight the significant role of circHomer1 in regulating cocaine reward and identify a novel molecular regulator of the actions of cocaine on the brain’s reward circuitry, providing a new strategy for treating drug addiction.
