Reality of auditory verbal hallucinations
Distortion of the sense of reality, actualized in delusions and hallucinations, is the key feature of psychosis but the underlying neuronal correlates remain largely unknown. We studied 11 highly functioning subjects with schizophrenia or schizoaffective disorder while they rated the reality of auditory verbal hallucinations (AVH) during functional magnetic resonance imaging (fMRI). The subject...
متن کاملAre auditory-verbal hallucinations associated with auditory affective processing deficits?
We investigated whether the presence of auditory-verbal hallucinations (AVH) was associated with impaired auditory affect perception. Controls, schizophrenia patients with a history of AVH (AVH) or with no history of AVH (NAVH) completed four perceptual auditory affect tasks. The tasks used either non-verbal/non-semantic or verbal/semantic stimuli. AVH patients showed significant impairments on...
متن کاملThe spatiotemporal pattern of auditory cortical responses during verbal hallucinations.
Functional magnetic resonance imaging (fMRI) studies can provide insight into the neural correlates of hallucinations. Commonly, such studies require self-reports about the timing of the hallucination events. While many studies have found activity in higher-order sensory cortical areas, only a few have demonstrated activity of the primary auditory cortex during auditory verbal hallucinations. I...
متن کاملReproducibility of brain activation during auditory verbal hallucinations
Previous studies investigated fMRI-guided repetitive Transcranial Magnetic Stimulation (rTMS) as an alternative treatment for auditory verbal hallucinations (AVH). This tailor-made treatment focuses at directing the rTMS coil to the location where hallucinatory activation is maximal, as identified with fMRI scans of individual patients. For the effective use of such treatment it is important to...
متن کاملA Psychological Model for Verbal Auditory Hallucinations
The present paper outlines a theoretical model that incorporates, systematizes and provides coherence to the most relevant data found in the scientific literature reviewed in relation to verbal auditory hallucinations. On the one hand, this paper distinguishes the onset and consolidation of global hallucinatory process from concrete episodes. On the other hand, it distinguishes between the stru...
