The Triple Network Model
Vinod Menon’s Triple Network Model — the Central Executive, Salience, and Default Mode networks, sometimes called the "triple brain" — read against this Corpus’s own Tree. Two of the three were already named on this Corpus’s tables before this page existed. Click any network below for its image, its anatomy, and its place on the Tree.

The Vertical Axis: Control, Switch, Foundation
The three networks do not scatter across the Tree; they trace a single line. Chesed and Geburah, the right and left DLPFC, flank the Middle Pillar as the bilateral executive pair — mercy’s expansive governance and severity’s analytical restriction, already named for exactly these hemispheres before the Triple Network Model entered this page. Tiphareth, the Tree’s literal center, is the switch. Yesod, one station further down the Middle Pillar, is the foundation the switch releases into when the executive is not needed. Kether through Tiphareth through Yesod through Malkuth was already this Corpus’s name for the axis of equilibrium; the three networks simply walk down three of its stations in order.
One further confirmation came from data already on this Corpus’s own table, not built for this page: Chesed, Geburah, and Tiphareth all carry the soul-register Ruach, the discursive and effortful mind. Yesod alone, one station lower, carries Nephesh, the vital and instinctual soul. The CEN and the SN — deliberate control and the felt sense of what matters — sit in the register of effortful mind. The DMN — mind-wandering, the dreaming self, the reservoir of image and instinct — sits one register down, in exactly the soul-level this Corpus had already called the seat of instinct and the dreaming mind.
What This Page Does and Does Not Claim
The anatomy is not in question. The Central Executive, Salience, and Default Mode networks are among the most replicated findings in human neuroimaging, with specific, well-documented nodes — DLPFC and posterior parietal cortex for the CEN, anterior insula and dorsal ACC for the SN, medial prefrontal cortex with posterior cingulate, precuneus, and angular gyrus for the DMN — and a well-evidenced switching dynamic between them, due to Vinod Menon’s 2011 synthesis and the large body of work since.
The correspondence to specific Sephiroth is this Corpus’s own symbolic reading, not a finding of the neuroscience. What can honestly be said for it: the Tiphareth–salience and Yesod–default-mode identifications were already written into this Corpus’s neurological table before this page was built, arrived at independently of any attempt to fit the Triple Network Model specifically — so their agreement with Menon’s framework, when the framework was finally brought to the page, is a real and recordable resonance, not a correspondence constructed to order.
