Neurophysiological and Behavioral Responses to Gambling Cues in Individuals with Internet Gambling Disorder: A VR-EEG-GSR Study.
Article in Brain sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundInternet Gambling Disorder (IGD) has become an important public health concern, yet relatively little is known about the combined neural, autonomic, and behavioral mechanisms underlying cue reactivity in immersive gambling environments. This study investigated whether individuals with IGD demonstrate altered neurophysiological and psychophysiological responses during a virtual reality (VR) gambling task.
methodsFifty-seven adults, including 28 participants meeting diagnostic criteria for IGD and 29 healthy controls, completed a standardized VR casino paradigm incorporating predetermined win, loss, and near-miss events. Electroencephalography (EEG), galvanic skin response (GSR), behavioral performance, and post-task craving were assessed simultaneously.
resultsCompared with healthy controls, the IGD group demonstrated significantly greater P300 amplitudes during win trials and enhanced late positive potential (LPP) responses following near-miss outcomes, indicating increased attentional allocation and sustained emotional processing of gambling-related cues. Skin conductance responses were also significantly higher in response to near-miss events, whereas overall skin conductance level and reaction time did not differ significantly between groups. Participants with IGD additionally exhibited greater engagement during the VR task and reported substantially higher craving following exposure to the gambling environment.
conclusionThese findings indicate that immersive VR combined with EEG and autonomic recordings provides a sensitive framework for detecting cue-reactivity associated with IGD. Although the findings should be interpreted in light of the relatively modest sample size and the use of a predominantly male sample, they suggest that immersive VR combined with EEG and autonomic recordings provides a sensitive framework for investigating cue reactivity associated with Internet Gambling Disorder. Integrating behavioral, physiological, and neural measures may improve understanding of the mechanisms underlying problematic gambling and inform future research on objective assessment strategies and intervention development.
