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 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 کاملFrequency-Specific Abnormalities of Intrinsic Functional Connectivity Strength among Patients with Amyotrophic Lateral Sclerosis: A Resting-State fMRI Study
The classical concept that amyotrophic lateral sclerosis (ALS) is a degenerative disorder characterized by the loss of upper and lower motor neurons is agreed. However, more and more studies have suggested the involvement of some extra-motor regions. The aim of this study is to investigate the frequency-related alteration pattern of intrinsic functional connectivity strength (FCS) at the voxel-...
متن کاملFrequency-specific electrophysiologic correlates of resting state fMRI networks
Resting state functional MRI (R-fMRI) studies have shown that slow (<0.1Hz), intrinsic fluctuations of the blood oxygen level dependent (BOLD) signal are temporally correlated within hierarchically organized functional systems known as resting state networks (RSNs) (Doucet et al., 2011). Most broadly, this hierarchy exhibits a dichotomy between two opposed systems (Fox et al., 2005). One system...
