Whole brain resting state functional connectivity abnormalities in schizophrenia.
BACKGROUND Schizophrenia has been associated with disturbances in brain connectivity; however the exact nature of these disturbances is not fully understood. Measuring temporal correlations between the functional MRI time courses of spatially disparate brain regions obtained during rest has recently emerged as a popular paradigm for estimating brain connectivity. Previous resting state studies ...
متن کاملResting-State Quantitative Electroencephalography Reveals Increased Neurophysiologic Connectivity in Depression
Symptoms of Major Depressive Disorder (MDD) are hypothesized to arise from dysfunction in brain networks linking the limbic system and cortical regions. Alterations in brain functional cortical connectivity in resting-state networks have been detected with functional imaging techniques, but neurophysiologic connectivity measures have not been systematically examined. We used weighted network an...
متن کاملResting-State Functional Connectivity Abnormalities in Adolescent Depression
Article history: Received 28 February 2017 Accepted 28 February 2017 Available online 3 March 2017 (Cullen et al., 2014). Chattopadhyay and co-workers examined differences in restingstate functional connectivity (rsFC) between adolescent patients with MDD andmatched healthy controls as well as changes in rsFC following cognitive behavioral therapy (CBT) (Chattopadhyay et al., 2017-in this issue...
متن کاملIncreased Resting-State Gamma-Band Connectivity in First-Episode Schizophrenia.
BACKGROUND Schizophrenia has long been suggested to represent a disorder with prominent neural dysconnectivity. Gamma-band oscillations are highly relevant in this context, due both to their proposed involvement in neuronal synchronization and to their association with neurotransmitter systems relevant for schizophrenia. Several task-related studies have confirmed reduced power and synchronizat...
متن کاملResting-state fMRI connectivity impairment in schizophrenia and bipolar disorder.
BACKGROUND Schizophrenia and bipolar disorder share aspects of phenomenology and neurobiology and thus may represent a continuum of disease. Few studies have compared connectivity across the brain in these disorders or investigated their functional correlates. METHODS We used resting-state functional magnetic resonance imaging to evaluate global and regional connectivity in 32 healthy control...
