Research focus
This article may help explain addiction science through research on opioid, cocaine, brain science, withdrawal. The source abstract begins by describing: “Evidence indicates that the anterior (aIC), but not posterior (pIC), insular cortex promotes cued reinstatement of cocaine seeking after extinction in rats.”
Key finding: Moreover, the incubation of craving results suggest that new contingency learning is necessary to recruit the aIC in cued heroin seeking.
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, 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.

This article may help explain addiction science through research on opioid, cocaine, brain science, craving. The source abstract begins by describing: “We recently reported that a conditioned stimulus (CS) memory retrieval-extinction procedure decreases reinstatement of cocaine and heroin seeking in rats and heroin craving in humans.”
Key finding: The UCS memory retrieval-extinction procedure has superior relapse prevention characteristics than the CS memory retrieval-extinction procedure and could be a promising method for decreasing relapse in human addicts.

This article may help explain addiction science through research on cocaine, brain science, craving, relapse. The source abstract begins by describing: “Cocaine use disorder represents a public health crisis with no FDA-approved medications for its treatment.”
Key finding: These findings suggest that gut bacteria, via their metabolites, are key regulators of drug-seeking behaviors, positioning the microbiome as a potential translational research target.

This article may help explain addiction science through research on cocaine, brain science, craving, relapse. The source abstract begins by describing: “One of the greatest challenges in treating addiction is preventing relapse during abstinence.”
Key finding: Such work has the potential to identify new therapeutic targets and to further our understanding of experience-dependent plasticity in the adult brain under normal circumstances and in the context of addiction.

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.
