Research in experimental psychology and Neuroscience has established how different CTBG circuits contribute to control of actions based on environmental circumstances and past learning history. There is also a large and growing body of evidence that misused substances, including alcohol, act on cells within these circuits. These actions promote acute intoxication and drug seeking and contribute to changes in behavior induced by chronic alcohol exposure, withdrawal and relapse. Alcohol exposure also influences which of the different CTBG circuits has the strongest influence on behavior.

Fifty-five adults aged 18–65 years were enrolled, including individuals with CP only (n = 20), AUD only (n = 14), CP + AUD (n = 8), and healthy controls (n = 13). Participants completed a self-report measure of IU and the Yale Pain Stress Test (YPST), an adaptation of the Cold Pressor Test, designed to elicit pain-related stress. Behavioral pain tolerance, subjective pain and alcohol craving were assessed across two experimental sessions, one with exposure to an ice-cold water stressor and the second with a warm-water control condition. Exposure to the pain-related stressor significantly reduced behavioral pain tolerance and increased subjective pain across all groups, and also heightened alcohol craving, particularly in individuals with AUD. IU moderated the pain experience during pain-related stress: in the CP + AUD group, higher IU was associated with lower pain tolerance, whereas in the AUD group, higher IU was correlated with greater pain tolerance. IU also moderated craving responses, with higher IU predicting increased craving in individuals with both CP and AUD.

Alcohol (EtOH) is one such factor that has been shown to increase tumor size and vascularization of melanomas in xenograft mouse models and invasion of breast cancer cells in vitro. Currently, whether EtOH exposure promotes glioma progression in vivo is unknown. Here, we induced fluorescently labeled gliomas in immune-competent mice by injecting and electroporating <em>Cre</em> + CRISPR plasmids to delete tumor suppressor genes in neural progenitors lining the right lateral ventricle. Asymptomatic tumor mice were exposed to EtOH or Air vapors via inhalation chambers for five days, followed by two days of rest, then another five days of exposure. This paradigm produced blood ethanol concentrations (BECs) similar to episodic binge drinking, averaging ∼200 mg/dL on the final day of exposure. We found that EtOH exposure acutely increased tumor vascularization and invasion to the contralateral hemisphere. Notably, EtOH-exposed male mice exhibited a significant decrease in survival compared to Air-exposed controls and EtOH-exposed female mice.
