Dorsal (sensory) RSNs. These networks were identified using a group ICA in a restricted region that just included the spinal cord. (Left) A sagittal section of our T1-weighted template depicting the location of the displayed transversal sections (gray lines) from C4 to T1 as well as the excellent overlap with the group spinal cord mask (yellow). (Right) The dorsal RSNs are arranged in anatomical level order with each column corresponding to one component. Both the restricted rostro-caudal extension of each component and the unilateral occurrence are clearly evident. Each RSN map is thresholded at FDR P < 0.05 and shown in rostral-caudal direction with the component ranking number at the bottom. Note that component ordering is based on the amount of variance each component explains (in decreasing order).
