Figure 3. Component types.

Representative spatial maps for noise and functional network subtypes used in the study including (1) eyeballs, (2) head motion, (3) ventricles, (4) primary visual cortex, (5) parieto-occipital cortex, and (6) ventral primary somatosensory cortex. For the “all noise types” models (not illustrated), criteria included signal outside of gray matter, high frequency time-courses, and the presence of rings or stripes that represent motion or scanner artifact.
