Auditory hallucinations in schizophrenia: what makes them real?
The human brain has the capacity to hallucinate but rarely, except in severe neuropsychiatric conditions such as schizophrenia, do they naturally predominate. The neural basis of auditory verbal hallucinations has been investigated using structural and functional neuroimaging techniques. So far, no studies have defined a model that explains why auditory hallucinations are perceived in the absence of an external stimulus. I will discuss some recent neuroimaging research into the pathogenesis of auditory hallucinations, which seeks to examine component perceptual processes that lead to an individual’s perception of auditory hallucinations as real auditory events.
