Consistent resting-state networks across healthy subjects
TLDR
Findings show that the baseline activity of the brain is consistent across subjects exhibiting significant temporal dynamics, with percentage BOLD signal change comparable with the signal changes found in task-related experiments.
The clinical use of structural MRI in Alzheimer disease
TLDR
The utility of structural imaging and other markers will be increased by standardization of acquisition and analysis methods, and by development of robust algorithms for automated assessment, as well as by research into other imaging and nonimaging markers.
Reduced resting-state brain activity in the "default network" in normal aging.
TLDR
This work examined the functional properties of brain networks based on spontaneous fluctuations within brain systems using functional magnetic resonance imaging to hypothesized that functional connectivity of intrinsic brain activity in the "default-mode" network (DMN) is affected by normal aging and that this relates to cognitive function.
Small-world networks and functional connectivity in Alzheimer's disease.
TLDR
Graph theoretical analysis was applied to matrices of functional connectivity of beta band-filtered electroencephalography (EEG) channels and it was demonstrated that AD is characterized by a loss of small-world network characteristics.
