Abnormal cingulate modulation of fronto-temporal connectivity in schizophrenia.

Functional neuroimaging provides a novel means of exploring neurophysiological function in schizophrenia. However, most of the studies that have been carried out report their findings in terms of regionally localized abnormalities. In this paper we propose an alternative method of data analysis that emphasizes global integration rather than isolated regional changes in response to psychological...

Abnormal superior temporal connectivity during fear perception in schizophrenia.

Patients with schizophrenia have difficulty in decoding facial affect. A study using event-related functional neuroimaging indicated that errors in fear detection in schizophrenia are associated with paradoxically higher activation in the amygdala and an associated network implicated in threat detection. Furthermore, this exaggerated activation to fearful faces correlated with severity of flat ...

Dynamic windowing reveals task-modulation of functional connectivity in schizophrenia patients vs healthy controls

Introduction Studying functional connectivity (correlations among voxels) among brain networks helps reveal important information about brain function in healthy and diseased brain. Being a major psychotic disorder, schizophrenia, is known to disrupt cognitive and motor functions and it has been shown to disrupt task-related functional networks during performance of certain tasks. Functional ne...

Dynamic functional connectivity analysis reveals transient states of dysconnectivity in schizophrenia

Schizophrenia is a psychotic disorder characterized by functional dysconnectivity or abnormal integration between distant brain regions. Recent functional imaging studies have implicated large-scale thalamo-cortical connectivity as being disrupted in patients. However, observed connectivity differences in schizophrenia have been inconsistent between studies, with reports of hyperconnectivity an...

Abnormal Asymmetry of Brain Connectivity in Schizophrenia

Recently, a growing body of data has revealed that beyond a dysfunction of connectivity among different brain areas in schizophrenia patients (SCZ), there is also an abnormal asymmetry of functional connectivity compared with healthy subjects. The loss of the cerebral torque and the abnormalities of gyrification, with an increased or more complex cortical folding in the right hemisphere may pro...
