Research Data from Peking University Sixth Hospital Update Understanding of Hallucinations (Decreased Broca-left supplementary motor area connectivity underlying auditory verbal hallucination: A resting-state NIRS study).

This article reports on a study investigating the neural mechanisms underlying auditory verbal hallucinations (AVH), a core symptom of schizophrenia, conducted by researchers at Peking University Sixth Hospital. Using functional Near-Infrared Spectroscopy (fNIRS), the study compared resting-state brain connectivity among healthy controls, schizophrenia patients with a history of AVH (AVHh+), and those without (AVHh-). The findings revealed significantly reduced functional connectivity between Broca's area and the left supplementary motor area in AVHh+ patients, suggesting this hypoconnectivity may serve as a trait-like marker of vulnerability to AVH. The research was supported by the National Natural Science Foundation of China and published in Translational Psychiatry. [Extracted from the article]
