THE NEUROSCIENCE OF AUDITORY HALLUCINATIONS

Abstract

A hallucination is a distortion of sensory perception with the same qualities of a real perception, but without external stimulation of a sensory organ. It is estimated that approximately 60% to 70% of patients with this disorder and other psychopathology and to have symptoms, despite its strong association with schizophrenia, many studies have shown that auditory hallucinations can also be measured in non-psychiatric population with rates many times greater than all psychotic disorders combined. Neuroimaging technologies have been widely used in an attempt to understand the brain regions and circuits involved in the genesis of hallucinations, and patients with schizophrenia has been studied more frequently. This article aims to review the literature on neuroscience have helped in the process of discovery processes involving auditory hallucinations. It is concluded that neuroimaging data have confirmed the expectation that the hallucinations involve changes in the activity of neural circuits known to be involved in normal hearing liguagem and its control, but the big question of how this altered activity arises, remains unanswered.
