Natural scenes viewing alters the dynamics of functional connectivity in the human brain

Abstract:

Spontaneous fMRI fluctuations are organized in large-scale spatiotemporal structures, or resting-state networks (RSN). However, it is unknown how task performance affects RSN dynamics. We use MEG to measure slow (~0.1Hz) coherent fluctuations of band-limited power (BLP), a robust correlate of RSN, during rest and movie observation and compare them to fMRI-RSN. BLP correlation, especially in αband, dropped in multiple RSN during movie although overall topography was maintained. Variability of ...
