| Research Abstract |
The aim of this study was to investigate the neural basis of auditory hallucination in schizophrenia. We analyzed the neural activities related to auditory hallucinations or the audio-visual integration process using new neurophysiological methods. We found that abnormalγ-band neural oscillation activities evoked during audio, visual and audio-visual integration were prominently involved in the neural basis of auditory hallucinations in schizophrenia. These results may contribute to the development of diagnoses, therapies and provide clues to the underlying cause of schizophrenia.
