When Broca Goes Uninformed: Reduced Information Flow to Broca's Area in Schizophrenia Patients With Auditory Hallucinations

Auditory-verbal hallucinations (AVHs) are frequently associated with activation of the left superior temporal gyrus (including Wernicke’s area), left inferior frontal gyrus (including Broca’s area), and the right hemisphere homologs of both areas. It has been hypothesized that disconnectivity of both interhemispheric transfer and frontal and temporal areas may underlie hallucinations in schizophrenia. We investigated reduced information flow in...
