Reality of Auditory Hallucinations in Schizophrenia
25 untreated urban living schizophrenics fulfilling the criteria of Feighner et al., having Schneiderian auditory hallucination were studied with the aim of examining the experienced reality of auditory hallucination and the influence on this reality of certain variables. It was found that the hallucinations were more real than unreal. Duration of illness, presence of anxiety prior to hallucina...
متن کاملIs gamma band EEG synchronization reduced during auditory driving in schizophrenia patients with auditory verbal hallucinations?
Auditory verbal hallucinations (AVH) in schizophrenia patients assumingly result from a state inadequate activation of the primary auditory system. We tested brain responsiveness to auditory stimulation in healthy controls (n=26), and in schizophrenia patients that frequently (n=18) or never (n=11) experienced AVH. Responsiveness was assessed by driving the EEG with click-tones at 20, 30 and 40...
متن کاملOscillatory Cortical Network Involved in Auditory Verbal Hallucinations in Schizophrenia
BACKGROUND Auditory verbal hallucinations (AVH), a prominent symptom of schizophrenia, are often highly distressing for patients. Better understanding of the pathogenesis of hallucinations could increase therapeutic options. Magnetoencephalography (MEG) provides direct measures of neuronal activity and has an excellent temporal resolution, offering a unique opportunity to study AVH pathophysiol...
متن کاملMapping auditory hallucinations in schizophrenia using functional magnetic resonance imaging.
BACKGROUND Perceptions of speech in the absence of an auditory stimulus (auditory verbal hallucinations) are a cardinal feature of schizophrenia. Functional neuroimaging provides a powerful means of measuring neural activity during auditory hallucinations, but the results from previous studies have been inconsistent. This may reflect the acquisition of small numbers of images in each subject an...
متن کاملRelationship of imprecise corollary discharge in schizophrenia to auditory hallucinations.
CONTEXT A forward model of intended thoughts and actions prepares sensory cortex for sensations that are a consequence of those actions. Imprecision of the corollary discharge in schizophrenia may contribute to the misperception of inner experiences and thoughts as "voices" or auditory hallucinations. OBJECTIVES To assess the precision of the forward model in schizophrenia using the N100 comp...
