Interhemispheric auditory connectivity: structure and function related to auditory verbal hallucinations
Auditory verbal hallucinations (AVH) are one of the most common and most distressing symptoms of schizophrenia. Despite fundamental research, the underlying neurocognitive and neurobiological mechanisms are still a matter of debate. Previous studies suggested that "hearing voices" is associated with a number of factors including local deficits in the left auditory cortex and a disturbed connect...
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 کاملReality 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 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 کاملVerbal self-monitoring and auditory verbal hallucinations in patients with schizophrenia.
BACKGROUND Contemporary cognitive models of auditory verbal hallucinations propose that they arise through defective self-monitoring. We used a paradigm that engages verbal self-monitoring to investigate this theory in patients with schizophrenia. METHODS Ten patients with auditory verbal hallucinations and delusions (hallucinators), eight patients with delusions but no hallucinations (non-ha...
