When we shift from the triune brain to the networked brain framework, we move from a model of separation and hierarchy into a living orchestration of interconnected intelligence. The triune brain—reptilian, limbic, and neocortical—was once a useful map to describe evolutionary layering, yet its structure implies order through control, with “higher” functions regulating and/or overriding “lower” instincts. This creates a somatic culture of regulation, restraint, and resilience—producing a body that survives through adaptation.
In contrast, the networked brain opens a field of dynamic integration, in which intelligence circulates through interdependent evolving systems rather than cascading down a chain of command. Networking the brain invites the soma into congruence—a state where each level of sensing, movement, and meaning participates simultaneously in the orchestration of living coherence.
From Hierarchy to Harmonic Networks
In the triune model, the brain-body is experienced as a stratified form: instinctual survival level (reptilian brain) beneath emotion level(limbic brain) beneath reasoning level (neocortex). Somatic work within this frame often moves “upward,” from regulation of primal drives toward refined awareness. It assumes that to evolve, we must ascend – Go Cortical!
The networked model dissolves this upward motion into mutual emergence. Intelligence is distributed through varying patterns of relationship—the brain is not a stack but a field. The soma expresses this transformation: rather than climbing through layers, we sense the lattice of connection that underlies all somatic expression. In this view, transformation does not occur through dominance or transcendence but through the synchronisation of interdependent processes.
Where the triune brain encourages a top-down approach (“control the nervous system to find calm”), the networked brain enables a whole-field coherence: a simultaneous calibration across perception, emotion, and intention. Deep Somatics grows from this coherence. It is no longer about regulating impulses, but about opening pathways of communication within the living body-field.
The Default Mode Network: The Field of Inner Continuity
The Default Mode Network (DMN) is the neural space of self-referencing, imagination, and autobiographical continuity. In Deep Somatic development, the DMN represents the inner ocean of presence—the felt continuity of “I Am” that threads through memory, imagery, and sense of identity.
When experienced through Deep Somatics, the DMN becomes a field of self-resonant awareness rather than mental narration. Its function shifts from re-running the past to holding the living continuity of being. Within this coherence, the soma experiences depth: a continuous current of self-sensing that flows beneath surface movement.
In the triune model, self is seen as emerging from the upper brain’s abstract capacity; in the networked model, self is sensed as distributed presence—felt through every cell, every rhythmic pulse, every vibration that contributes to the experience of “being one’s body.”
Thus, the DMN in Deep Somatics is not an egoic storyteller, but a ground of inner field-awareness through which the soma perceives itself as whole.
The Salience Network: The Bridge of Aliveness
The Salience Network (SN) operates as the attentional filter—the coordinator between internal states and external events, deciding what awareness focuses on. It unites interoception (inner sensing) and exteroception (outer sensing), allowing us to feel both the texture of the inner body and the pulse of the outer world as a single continuum.
In Deep Somatics, this network becomes the living pulse of discernment—the somatic intelligence that recognises what is meaningful now. It transforms automatic reactivity into presenced activity: a dynamic sensing of where energy wants to flow next.
Through this bridge, we experience aliveness as orientation. The Salience Network is where movement begins—where awareness leans toward what wants to emerge. Instead of hierarchical instruction (“move this muscle to achieve this goal”), movement becomes relational dialogue between body and world.
The triune brain could only frame this as limbic reactivity versus neocortical control. The networked brain reveals a third path—resonant participation—where feeling, sensing, and knowing are co-active. The Salience Network thus mediates the somatic field’s shift from control to communion.
The Central Executive Network: The Conductor of Intention
The Central Executive Network (CEN) governs focused attention, decision, and active memory—the capacity to hold and enact intention. In the old model, this would correspond to the “upper brain,” but the networked model transforms its role: rather than commanding, it integrates and orchestrates.
In Deep Somatics, the CEN is not a controlling authority; it is the clarity of directed flow. It gathers the distributed intelligence of the soma into purposeful expression. From this field, the soma becomes lucid in motion—action arising naturally from coherence rather than imposed will.
The CEN aligns inner continuity (DMN) and outer salience (SN) into creative enactment. It is where the deep inner current of being meets the clarity of directed becoming. Within this triadic orchestration—Default, Salience, Executive—the soma attunes to a living equilibrium: presence sensing itself, orientation opening, and action aligning.
The Emergence of Deep Somatic Coherence in the Networked Brain
As these three networks interweave, a new somatic intelligence emerges—one that operates through reciprocal synchronicities rather than top-down regulation. The body becomes a distributed field of knowing, where perception and action are continually co-creating.
Deep Somatic development flourishes in this field because it no longer seeks to fix or regulate the various layers of the nervous system; rather it invites coherence across the networked landscape of the living brain-body system. The triune model’s segmentation—instinct versus emotion versus reason—yields to the networked model’s symphonic integration of the whole.
This redefines somatic depth. Depth is no longer found “beneath” the surface layers of behaviour or awareness—it is found in the synchrony of interconnection. A networked soma is a resonant living body of consciousness, each network pulsing within the same field of living intelligence.
From Resilient to Congruent Growth
In the triune era, somatic growth was focused on resilience: learning to adapt, regulate, and largely survive the dissonance between layers. In the networked era, somatic growth becomes congruent: aligning inner and outer frequencies into a coherent field of being and becoming.
Where Resilience involved returning to balance after periods of imbalance; congruence is about continuously remaining in harmonic fluid alignment. The networked brain supports this by continually adjusting relational coherency rather than relying on static hierarchy fixed forms.
Through the integration of DMN, SN, and CEN, Deep Somatics cultivates a living architecture of congruence. Presence (DMN), discernment (SN), and enactment (CEN) flow together as a unified field. The soma becomes a living network of attuned intelligence—fluid, precise, awake.
In Essence
The shift from the old layered triune brain to the new networked brain is the shift from command and control to communion and coherence. It opens the gateway for Deep Somatics to evolve beyond regulation into resonant participation—a direct expression of the body as a multidimensional field of knowing.
The Default Mode Network enables the deep inner sense of continuity;
The Salience Network awakens aliveness and relational orientation;
The Central Executive Network aligns intention into lucid action.
Together, they form a new neural triad of congruence—a living system that expresses the deep somatic state of wholeness.
Through this new major triadic orchestration, the soma becomes not a layered organism, but a living network of consciousness—breathing, sensing, and expressing as one unified, luminous field.
