Abstract

|
Auditory hallucinations are cardinal feature of psychosis. But the mechanism of hallucinated speech is unknown. The hypothesis that these hallucinations arise from pathologically altered brain monitoring system underlying speech perception is influential. With the help of rapidly developing neuroimaging study technologies, many researchers have been finding new organic deficits in the hallucinated schizophrenic patient’s brain. In this article, we reviewed the general appearance of hallucination, a computer simulation model of hallucination and several neuroimaging study findings in hallucinating schizophrenic patients. In conclusion, we presented the presumptive mechanism of hallucination based on the anatomical dysfunction of schizophrenia.
