Cortical networks shift their dynamic functional connectivity along a spectrum that tracks the level of external to internal attention demanded by tasks. Networks often grouped into a single task-positive network show divergent responses along this axis, suggesting that defining a single task-positive network is misleading. Somatosensory and visual networks exhibit strong phase shifting along this attentional spectrum. Results were robust at both group and individual levels, supporting network dynamics as a potential individual biomarker. This work provides the first spectrum of dynamic network relationships across an axis of attention, using fMRI data from tasks including moving dots, visual working memory, congruence tasks, resting states, mindfulness meditation, and TV watching.
