Network transitions vary across functional states. 7-Network clustering parcellations were computed separately for all 14 tasks (N = 48). Heatmap indicates number of tasks (out of 14) for which a transition between networks falls at a given location on the lateral left hemisphere. Black lines indicate the location of network boundaries for the three particular tasks shown. Some border locations are highly consistent across tasks—e.g. transitions occurring near pre-central cortex and between inferior parietal and occipital regions. Other locations consistently do not contain network transitions, for instance in parts of medial prefrontal, somatomotor and occipital cortex. Certain regions in prefrontal, temporal and parietal cortex exhibit considerable variability of network topography across tasks. The agreement between any given task and the other 13 tasks' network boundary locations was similar across all tasks (mean overlap was 64–67%). The passive fixation task (fixate) agreement to the other tasks was not exceptional in this respect (mean overlap = 66%). h, hard.
