Research focus
This article may help explain addiction science through research on nicotine, dopamine, brain science, withdrawal. The source abstract begins by describing: “Corticotropin-releasing factor (CRF) and dopamine (DA) are critical for stress and motivation, respectively.”
Key finding: These results link the brain reward and stress systems in the same brain region to signaling of the negative motivational effects of nicotine withdrawal.
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, 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, 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, dopamine, brain science, withdrawal. The source abstract begins by describing: “Opioid abuse is a rapidly growing public health crisis in the USA.”
Key finding: Low-mGluR2 expression in the brain may therefore be a risk factor for the initial development of opioid abuse and addiction.

This article may help explain addiction science through research on alcohol, cannabis, nicotine, dopamine. The source abstract begins by describing: “In this Opinion article, Nutt and colleagues examine the history of and current evidence for the dopamine theory of addiction.”
Key finding: These observations have implications for understanding reward and treatment responses in various addictions.

This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Persistent vulnerability to drug-seeking is driven by enduring synaptic adaptations, yet current μ-opioid receptor-targeting pharmacotherapies provide limited efficacy against these neuroadaptations.”
Key finding: By targeting a pathway independent of classical opioid receptor signaling, CA4 inhibition represents a mechanistically distinct strategy that may reduce relapse vulnerability in OUD.
