Theory of Self‑Anchors: Architecture of a Stable Anchor and Dynamic Reference‑Frame Switching
Zenodo (CERN European Organization for Nuclear Research) April 28, 2026 Ilya Tarasov
The self is not only a narrative but also involves a stable self-anchor, bodily grounding, and rhythm-generating dynamics of the retrosplenial cortex. The stable self-anchor relates to the precuneus and posterior cingulate cortex, with a marker being the balance of glutamate-glutamine complex and GABA, assessed via proton magnetic resonance spectroscopy and linked to functional connectivity with the medial prefrontal cortex. Bodily grounding involves coupling between the posterior cingulate and insula, along with the temporoparietal junction, self-location, and body ownership. Rhythm-generating dynamics describe retrosplenial delta and theta activity during reference-frame switching; abnormal patterns appear in dissociative states. Depersonalization tests the stable self-anchor, and ketamine-induced dissociation tests pathological rhythm dynamics. The theory predicts partial dissociation among these axes' markers across tasks, symptoms, and pharmacological states.
