Full Text : COPYRIGHT 2011 Copyright © Massachusetts medical examination Society Byline: Steven Dubovsky, MD Insights into the neurobiology of auditory hallucinations in dementia praecox close to schizophrenia patients hear voices, but researchers have not subtle the neurobiology behind the hearing of voices that are not nonpareils own, precept things that one does not consciously think. These researchers used functional magnetised plangency imaging to investigate the contributory role of active connections amidst regions involved in processing wrangle. Participants were 32 patients with schizophrenia come by auditory hallucinations of voices at least once a day for the past month (11 with hallucinations every 3 transactions or less), 24 schizophrenia patients who had not heard voices for at least the past 5 years, and 23 healthy controls. entirely patients were neurologically intact, and all but 3 patients were taking antipsychotic drugs. In analyses cor recting 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 window dressing gyrus, and the putamen. Comment: Hyperactivity of a corticostriatal circuit involved in generating reference might be secondary to the experience of repeated hallucinations. However, fluctuations of sense activity in association with frequent hallucinations and similar degrees of brace in frequently and less-frequently hallucinating patients suggest that a cocktail dress of intragroup speech generates auditory hallucinations of voices. In nonhallucinating patients, partial disconnect of frontotemporal and frontostriatal circuits that generate speech may block the conversion of ingrained speech to hallucinations. The intensity of activity in these systems might extend to how hallucinated thoughts are converted to someone elses voice and contain tenderness that patients do no! t identify as their own.
