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

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

It has been observed by various groups that signal intensities in a time course of functional
magnetic resonance imaging (fMRI) images in a resting human brain vary by about 1–2 …

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 …

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

Functional magnetic resonance imaging (FMRI) is a new, noninvasive imaging tool thought
to measure changes related to regional cerebral blood flow (rCBF). Previous FMRI studies …

Functional magnetic resonance imaging (fMRI) is an emerging methodology for studying
regional brain function in vivo at relatively high spatial and temporal resolution. Because …

Cortical functional connectivity, as indicated by the concurrent spontaneous activity of
spatially segregated regions, is being studied increasingly because it may determine the …

The cerebral cortex is anatomically organized at many physical scales starting at the level of
single neurons and extending up to functional systems. Current functional magnetic …

We investigated large-scale systems organization of the whole human brain using functional
magnetic resonance imaging (fMRI) data acquired from healthy volunteers in a no-task or …
