Auditory hallucinations (AHs) are a common symptom of schizophrenia and contribute significantly to disease burden. Research on schizophrenia and AHs is limited and fails to adequately address the effect of AHs on resting EEG in patients with schizophrenia. This study assessed changes in frequency bands (delta, theta, alpha, beta) of resting EEG taken from hallucinating patients (n = 12), nonhallucinating patients (n = 11), and healthy controls (n = 12). Delta and theta activity were unaffected by AHs but differed between patients with schizophrenia and healthy controls. Alpha activity was affected by AHs: nonhallucinators had more alpha activity than hallucinators and healthy controls. Additionally, beta activity was inversely related to trait measures of AHs. These findings contribute to the literature of resting eyes closed EEG recordings of schizophrenia and AHs, and indicate the role of delta, theta, alpha, and beta as markers for schizophrenia and auditory hallucinations.

幻觉和非幻觉精神分裂症患者静息脑电图的变化

幻听 (AHs) 是精神分裂症的常见症状，对疾病负担有显着影响。关于精神分裂症和 AHs 的研究是有限的，未能充分解决 AHs 对精神分裂症患者静息脑电图的影响。该研究评估了从幻觉患者 (n = 12)、非幻觉患者 (n = 11) 和健康对照 (n = 12) 中获取的静息脑电图频段 (delta、theta、alpha、beta) 的变化。Delta 和 theta 活动不受 AH 的影响，但精神分裂症患者和健康对照者之间存在差异。α 活性受 AH 影响：非幻觉者比幻觉者和健康对照者具有更多的 α 活性。此外，β 活动与 AH 的特征测量呈负相关。
