Teoria polivagale/en

The polyvagal theory is a model of the autonomic nervous system proposed starting in 1994 by Stephen W. Porges, an American neuroscientist. The model describes the autonomic system not as a two-arm scale (sympathetic versus parasympathetic) but as a hierarchy of three phylogenetically stratified circuits, governed in real time by a process of preconscious evaluation of environmental safety that Porges calls neuroception.

The theory spread very rapidly beyond academic psychophysiology — into trauma psychotherapy, body medicine, and somatic clinical practice — because it provides a unifying neurophysiological language for phenomena that previous traditions described in a fragmented way: traumatic freeze, social engagement, mobilized activation, trance states, and dissociative responses. For the Paret Method, the polyvagal theory is the neurophysiological grammar that allows us to read in contemporary terms what the tradition of European magnetism had described phenomenologically a century and a half earlier — and what Eastern initiatic traditions (yoga, tantra, Taoism, Tibetan paths) had observed and trained systematically long before. The three-circuit architecture that Porges identifies anatomically corresponds precisely to the ternary structure of the living being described by the three Indian guṇa (rajas, sattva, tamas), by the Paracelsian Tria Prima (Sulfur, Mercury, Salt), and by other converging triads (three Ayurvedic doṣa, three centers of the enneagram). For the reader coming from an Eastern practice or a Western contemplative tradition, the polyvagal theory does not replace the familiar vocabulary: it adds the anatomical and measurable dimension to the description, articulating through distinct nerve circuits what the traditions describe through state qualities. For the articulated convergence, see Dall'ermetico al neurologico — corrispondenze.

The Three Circuits

Ventral vagal circuit (myelinated)

This is the most recent circuit in phylogenetic terms, exclusive to mammals. It connects the heart, lungs, face, voice, and middle ear. It is the circuit of social engagement, safety, and bonding. When active, the person is present, communicative, and in contact. It is the circuit upon which the Integral Presence of the Method and the fascinator's engagement with the subject rest.

Sympathetic circuit

The intermediate circuit in phylogenetic terms. It mobilizes energy for action. Activated in response to non-survival threat, it produces fight and flight responses. In the fascinatory state and in many activated trance states, it is modulated but not turned off.

Dorsal vagal circuit (unmyelinated)

The phylogenetically oldest circuit, shared with reptiles. It produces immobilization, conservation, and hypometabolism. In defensive mode, it generates traumatic freeze and dissociation; in non-defensive mode, it supports states of tonic quiet, deep absorption, and motionless ecstasy.

Neuroception

The term neuroception indicates the process, constantly active and largely preconscious, by which the nervous system evaluates internal and external signals to establish the level of environmental safety. The transition between the three circuits is not a voluntary choice: it is the result of this evaluation. For the fascinator, working with the subject's neuroception — through gaze, voice, touch, posture, and proxemics — is the main operational mechanism of state induction.

Recognitions in Historical Traditions

The anatomical identification of the three circuits — which makes the polyvagal theory a specifically twentieth-century model — was not available to previous traditions. However, the functional description of the same three modalities of the living being — warm active expansion, fluid mediation, stable containment — is an anthropological constant documented in independent traditions and distant eras:

• Yoga and Sāṃkhya: the three guṇa — rajas (activation, movement, passion), sattva (clarity, balance, mediating intelligence), tamas (stable inertia, containment, grounding). See Guna e Tria Prima for the precise comparison.
• Ayurveda: the three doṣa — vāta (movement, wind), pitta (heat, transformation), kapha (stability, structure).
• Traditional Chinese medicine: the triad of jing-qi-shen and the operational organization of the three dantian.
• Paracelsian alchemy and European Hermeticism: the Tria Prima (Sulfur, Mercury, Salt), articulated in the six character types of the Method through binary combination.
• Contemporary Enneagram: the three centers (head, heart, gut) of the Naranjo and Riso-Hudson school.
• Hesychast Patristics: the triad nous / thymos / epithymia (intelligence, ardor, desire) as planes of the guarded heart.

These convergences do not reduce one tradition to another. They show that the ternary structure of the autonomic nervous system that Porges identifies anatomically is a structure recognized — with different levels of technical articulation — by every tradition that has developed a systematic observation of the living being.

Relevance for the Paret Method

The polyvagal theory is central to the third axis of the Method for three converging reasons:

1. It provides the neurophysiological reading of historically documented fascination: what Luys describes in 1890 at the Charité — anesthesia, catalepsy, conscious automatism — is readable as a specific configuration of polyvagal transitions.
2. It allows reading human typologies (six types, Tria Prima, Eight Fixations, enneagrams) as stable polyvagal configurations rather than as abstract categories.
3. It provides measurable operational tools (HRV, vagal tone, respiratory modulation) for practice and training.
