FIG. 1.

The brain-state centroids, Sessions 1 and 2 without GSR (A) and with GSR (B). Brain-state centroids are presented in the sagittal (x = 0), axial (z = 44), and coronal (y = −16) planes. In all figures when referring to the states derived without GSR, brain state 1 = DMN deactivation, brain state 2 = DMN activation, brain state 3 = universal deactivation, and 4 = universal activation. In all figures when referring to the states derived with GSR, brain state 1 = DMN deactivation, 2 = DMN activation, 3 = motor deactivation, and 4 = motor activation. The scale (shown to the right of each row) is identical for all images. DMN, default mode network; GSR, global signal regression.
