Full Text : COPYRIGHT 2011 Copyright © Massachusetts medical examination Society Byline: Steven Dubovsky, MD Insights into the neurobiology of auditory hallucinations in schizophrenia close to schizophrenia patients hear voices, but researchers have not subtle the neurobiology behind the hearing of voices that are not nonpareils own, utter things that one does not consciously think. These researchers used functional magnetized plangency imaging to investigate the contributory role of active connections amidst regions involved in processing wrangle. Participants were 32 patients with schizophrenia adopt by auditory hallucinations of voices at least once a day for the past month (11 with hallucinations every 3 proceeding or less), 24 schizophrenia patients who had not heard voices for at least the past 5 years, and 23 healthy controls. only patients were neurologically intact, and all but 3 patients were taking antipsychotic drugs. In analyses correcting for the complexity of interactions between sensation regions, researchers found that hallucinating patients had a hyperactive loop between Brodmann area 45/46 in the Wernicke region, other parts of the left inferior frontlet gyrus, and the putamen.

Comment: Hyperactivity of a corticostriatal circuit involved in generating dustup might be secondary to the experience of repeated hallucinations. However, fluctuations of spirit activity in association with frequent hallucinations and similar degrees of energizing in frequently and less-frequently hallucinating patients suggest that a subject of intragroup speech g enerates auditory hallucinations of voices. ! In nonhallucinating patients, partial disconnection of frontotemporal and frontostriatal circuits that generate speech may block the conversion of knowledgeable speech to hallucinations. The intensity of activity in these systems might gibe how hallucinated thoughts are converted to someone elses voice and contain affectionateness that patients do not identify as their own.
