Thus, the present study aimed to investigate neuronal connectivity in patients with IGD and to clarify the neurophysiological features of this population by comparing their EEG data with those of AUD patients and HCs. AUD was selected as a traditional SUD because disruptions in the functional brain networks of AUD patients have been repeatedly examined33–35. Previous studies have suggested that IGD is a behavioral addiction that has similarities and differences with AUD, which is a depressant SUD36, 37. However, to the best of our knowledge, no direct comparisons of EEG coherence in IGD and AUD patients have been conducted to date.
