Hallucinations are a psychopathological phenomenon with neuropsychological, neuroanatomical and pathophysiological correlates in specific brain areas.They can affect any of the senses, but auditory and visual hallucinations predominate.Verbal hallucinations reveal no gross organic lesions while visual hallucinations are connected fr6122 to defined brain lesions.
Functional neuroimaging shows impairments in modality specific sensory systems with the hyperactivity of the surrounding cerebral cortex.Disinhibition and expansion of the inner speech was noted with impaired internal monitoring in auditory verbal hallucinations.The subcortical areas and modal-specific tanguray covington associative cortex and cingulate cortex are essential for the occurrence of hallucinations.
