A 3D image of the dorsal nexus. (A) Left (−24, 35, 28). (B) Right (18, 34, 29). The nexus was created from a conjunction analysis of the overlap of the areas of significantly increased connectivity among the three networks arising from seeds placed in the DLPFC, precuneus, and subgenual ACC. The individual connectivity maps for these seed regions are shown in Fig. 2. The nexus is comprised primarily of medial BA9, a portion of the ACC (BA32), and a small portion of medial BA8.
