Fig. 5: Spatial distribution and tSNR of human components.

A Probability map showing the number of components in which each voxel was active across the 14 functional networks (thresholded as indicated in Fig. 4). High-frequency recruitment was observed in auditory and visual areas, with sparse representation in somatosensory and ventral temporal cortex. B Mean tSNR map across all human participants. Visual inspection confirms that functional component distributions were not solely determined by tSNR patterns. Both maps are projected onto inflated and flat surface representations of the human brain, as well as onto coronal slices from an anatomical template in MNI space. White outlines indicate cortical areas based on the Human Connectome Project’s multi-modal parcellation atlas94.
