Reproducibility 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 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 کاملActivation of Heschl’s Gyrus during Auditory Hallucinations
Apart from being a common feature of mental illness, auditory hallucinations provide an intriguing model for the study of internally generated sensory perceptions that are attributed to external sources. Until now, the knowledge about the cortical network that supports such hallucinations has been restricted by methodological limitations. Here, we describe an experiment with paranoid schizophre...
متن کاملTime course of regional brain activation associated with onset of auditory/verbal hallucinations.
The time course of brain activation prior to onset of auditory/verbal hallucinations was characterised using functional magnetic resonance imaging in six dextral patients with schizophrenia. Composite maps of pre-hallucination periods revealed activation in the left anterior insula and in the right middle temporal gyrus, partially replicating two previous case reports, as well as deactivation i...
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...
