BACKGROUND AND PURPOSE: In subjects performing no specific cognitive task (“resting
state”), time courses of voxels within functionally connected regions of the brain have high …

BACKGROUND AND PURPOSE: In subjects who are performing no prescribed cognitive task,
functional connectivity mapped with MR imaging (fcMRI) shows regions with synchronous …

Low frequency oscillations, which are temporally correlated in functionally related brain regions,
characterize the mammalian brain, even when no explicit cognitive tasks are performed. …

BACKGROUND AND PURPOSE: Regional cerebral blood flow fluctuates synchronously in
corresponding brain regions between the hemispheres. This synchrony implies neuronal …

Collecting comprehensive data sets of the same subject has become a standard in neuroscience
research and uncovering multivariate relationships among collected data sets have …

A new approach in studying interregional functional connectivity using functional magnetic
resonance imaging (fMRI) is presented. Functional connectivity may be detected by means of …

BACKGROUND AND PURPOSE: With functional connectivity functional MR imaging,
covariance in signal intensity has been shown in functionally related regions of brain in …

Rationale The default mode network (DMN), one of several resting-state networks (RSN) in
the brain, is thought to be involved in self-referential thought, awareness, and episodic …

Amnestic mild cognitive impairment (aMCI) is a syndrome associated with faster memory
decline than normal aging and frequently represents the prodromal phase of Alzheimer's …

BACKGROUND AND PURPOSE: Independent component analysis (ICA), unlike other methods
for processing functional MR (fMR) imaging data, requires no a priori assumptions about …
