Spectral Diversity in Default Mode Network Connectivity Reflects Behavioral State

Published in:┬áJournal of Cognitive Neuroscience, Volume 30, Issue 4, April 2018, 526-539 Abstract “Default mode network (DMN) functional connectivity is thought to occur primarily in low frequencies (<0.1 Hz), resulting in most studies removing high frequencies during data preprocessing. In contrast, subtractive task analyses include high frequencies, as these are thought to be task relevant. An emerging line of research explores resting fMRI data at higher-frequency bands, examining the possibility that functional connectivity is a multiband phenomenon. Furthermore, recent studies suggest DMN involvement in cognitive processing; however, without a systematic investigation of DMN connectivity during tasks, its functional contribution to… Read More
