To investigate the neural correlate of fMRI
resting-state networks (RSNs), we recorded and analyzed
large-scale ECoG data from macaques during eyes-closed
wakefulness, sleep, and two anesthetic regimes. A
data-driven analysis on co-variations of spontaneous
power fluctuations revealed 8 spatial patterns that
corresponded closely to previously reported RSNs. These
patterns were similar across spectral frequency bands
and behavioral conditions. We conclude that fMRI RSNs
reflect the spatial organization of spontaneous
broadband neural activity, which appears to be a core
aspect of the brains physiology that is preserved
across various states of consciousness.
