This study investigates whether resting-state EEG signatures can predict the treatment efficacy of transcranial alternating current stimulation (tACS) for refractory auditory hallucinations in schizophrenia. Resting-state EEG data from patients were analyzed to identify features associated with clinical response. The results highlight high-gamma EEG characteristics, especially in the right hemisphere, as informative markers for predicting tACS response, with a reported recognition accuracy of 93.87%. These findings suggest that rsEEG-based biomarkers may support personalized neuromodulation decisions for patients with refractory auditory hallucinations.
