Fig. 3: Anatomy of PH-network and of other identified networks.

All brain networks are shown after spatial standardization. A PH-network identified in previous work³⁴ and used here to compute online NF-signal. Major clusters are seen on the right posterior superior temporal sulcus (pSTS), the bilateral inferior parietal lobule (IPL) with focus on the supramarginal gyri (SMG), the right dorso-lateral prefrontal cortex (dlPFC), the middle prefrontal cortex (including part of the supplemental motor area: SMA), the left dlPFC, the left precentral gyrus (PrC), the body of the caudate on the right, and in the cerebellum, the left Crus I and II. Deactivations are observed over the cuneus and occipital gyrus. B PH-network as identified by CAP analysis in the current data. C Overlap between the PH-network as recovered previously³⁴ and the PH-network recovered here, showing that the latter recovers every major cluster of the former. D The sensorimotor⁺ network represents mostly sensory processing. Major activation clusters can be seen bilaterally over the sensory cortex (post central gyri, PsC), SMA, pre-motor cortex (pmC) pSTS, and supra-marginal gyri (SM). Major cluster deactivations are also seen bilaterally for the middle temporal gyri (MTG), medial and superior frontal gyri (mSFG, SFG), angular gyri, and posterior cingulate cortex (PCC). E The sensorimotor^- network is characterized by the pairing of bilateral deactivations of the sensory cortex, and by activations over four main cluster of the PH-network all on the right: the pSTS, the dlPFC, the mPFC, and the AG. F The DMN^- network is characterized by deactivations of the PCC, bilateral AG, bilateral superior frontal gyri, and mPFC. It is also accompanied by activations over the PH-network clusters, including: SMA, and dlPFC (more prominently on the right).
