Background
The pathophysiology of auditory verbal hallucinations remains poorly understood.
AimsTo characterise the time course of regional brain activity leading to auditory verbal hallucinations.
MethodDuring functional magnetic resonance imaging, 11 patients with schizophrenia or schizoaffective disorder signalled auditory verbal hallucination events by pressing a button. To control for effects of motor behaviour, regional activity associated with hallucination events was scaled against corresponding activity arising from random button-presses produced by 10 patients who did not experience hallucinations.
ResultsImmediately prior to the hallucinations, motor-adjusted activity in the left inferior frontal gyrus was significantly greater than corresponding activity in the right inferior frontal gyrus. In contrast, motor-adjusted activity in a right posterior temporal region overshadowed corresponding activity in the left homologous temporal region. Robustly elevated motor-adjusted activity in the left temporal region associated with auditory verbal hallucinations was also detected, but only subsequent to hallucination events. At the earliest time shift studied, the correlation between left inferior frontal gyrus and right temporal activity was significantly higher for the hallucination group compared with non-hallucinating patients.
ConclusionsFindings suggest that heightened functional coupling between the left inferior frontal gyrus and right temporal regions leads to coactivation in these speech processing regions that is hallucinogenic. Delayed left temporal activation may reflect impaired corollary discharge contributing to source misattribution of resulting verbal images.

The time course of brain activation prior to onset of auditory/ verbal hallucinations was characterised using functional magnetic resonance imaging in six dextral patients with schizophrenia. Composite maps of pre-hallucination periods revealed activation in the left anterior insula and in the right middle temporal gyrus, partially replicating two previous case reports, as well as deactivation in the anterior cingulate and parahippocampal gyri. These findings may reflect brain events that trigger or increase vulnerability to auditory/verbal hallucinations.

Multidisciplinary studies indicate that auditory hallucinations may arise from speech perception neurocircuitry without disrupted theory of mind capacities. Computer simulations of excessive pruning in speech perception neural networks provide a model for these hallucinations and demonstrate that connectivity reductions just below a “psychotogenic threshold” enhance information processing. These data suggest a process whereby vulnerability to schizophrenia is maintained in the human population despite reproductive disadvantages of this illness.
