An MRI time course of 512 echo‐planar images (EPI) in resting human brain obtained every 250 ms reveals fluctuations in signal intensity in each pixel that have a physiologic origin. Regions of the sensorimotor cortex that were activated secondary to hand movement were identified using functional MRI methodology (FMRI). Time courses of low frequency (<0.1 Hz) fluctuations in resting brain were observed to have a high degree of temporal correlation (P < 10−3) within these regions and also with… 
Resting-state brain networks in functional Magnetic Resonance Imaging (MRI)
The first successful study of brain spontaneous fluctuations by BOLD fMRI was performed by Biswal and colleagues, who computed the correlation between the time course of a seed region and all brain voxels in the absence of any experimental task.

Two recently developed approaches based on the time courses and the spatial patterns of simultaneously acquired EEG and fMRI data are compared to search and identify the electrophysiological correlates of spontaneous fMRI fluctuations.
Real time BOLD functional MRI neuro-feedback affects functional connectivity
The presence of the neuro-feedback of the activation in the hand motor area not only induces correlations between the visual and motor areas, but also increases basal ganglia involvement and bilateral motor cortex connectivity.
Cocaine administration decreases functional connectivity in human primary visual and motor cortex as detected by functional MRI
It is suggested that the observed changes in low frequency components after acute cocaine administration during a resting, no‐task situation may be used as a baseline reference source when assessing the effects of cocaine on task‐driven activation or on mesolimbic dopamine pathways.
Vascular Coupling in Resting-State FMRI: Evidence from Multiple Modalities
Findings raise a critical question of whether a large portion of rs-fMRI signals can be attributed to the vascular effects produced from upstream changes in cerebral hemodynamics.
A Review of Method and Approaches for Resting State fMRI Analyses
This article presents a review and comparison of various methods and algorithms for analyzing the functional connectivity of the human brain in resting state, developed in the world, based on an analysis of the literature.
Functional Connectivity Mapping for Correlated Resting State Image Volumes
Functional magnetic resonance imaging measures the changes in blood flow and blood oxygenation in the brain related to neural activity of human beings or other animals to reveal a baseline or a default fundamental in understanding human brain functions.

Functional magnetic resonance imaging of complex human movements
Six right-handed healthy subjects were scanned while they performed self-paced simple and complex finger movements with the right and left hands, and preliminary results are consistent with hierarchical models of voluntary motor control.
Processing strategies for time‐course data sets in functional mri of the human brain
The most effective method for image processing involves thresholding by shape as characterized by the correlation coefficient of the data with respect to a reference waveform followed by formation of a cross‐correlation image.
Functional Connectivity: The Principal-Component Analysis of Large (PET) Data Sets
The results suggest that the variance in neurophysiological measurements, introduced experimentally, was accounted for by two independent principal components and highlighted an intentional brain system seen in previous studies of verbal fluency.
Spontaneous waves of cerebral blood flow associated with a pattern of electrocortical activity.
The results indicate that a population of local cortical neurons, probably driven from subcortical pacemakers, when excited, elicits local cerebrovascular vasodilation in spinalized rats anesthetized with 1.5% isoflurane.
Supplementary motor area and other cortical areas in organization of voluntary movements in man.
It is suggested that the supplementary motor areas are programming areas for motor subroutines and that these areas form a queue of time-ordered motor commands before voluntary movement are executed by way of the primary motor area.
Location of hand function in the sensorimotor cortex: MR and functional correlation.
The hand function area in the sensorimotor cortex is easily understood with its characteristic shape in axial MR scan, and the comparison of MR and positron emission tomography data clearly show anatomic correlations.
Neuronal assemblies
The concept of neuronal assembly as it has appeared in selected portions of the literature is examined and it is shown that the dynamic firing correlation can be caused either by dynamic changes in neuronal connection strengths or by the effects of an unobserved (large) pool of other neurons.
