The Naked Insula: Interoceptive Collapse, Symbolic Defense, and Neuropsychoanalytic Semiotics

Psychoanalytic and phenomenological accounts of anxiety distinguish between raw bodily disquiet and top-down symbolic structures—morality, faith, and meaning—that subjects erect to contain it. We propose a neuropsychoanalytic model mapping this distinction onto two interacting neural registers: a bottom-up interoceptive circuit centered on the anterior insula and Salience Network (SN), and a top- down regulatory circuit centered on the ventromedial prefrontal cortex (vmPFC), dorsolateral prefrontal cortex (dlPFC), and Default Mode Network (DMN). Bringing Heidegger’s Angst, Kierkegaard’s decision, Kohut’s disintegration anxiety, and Lacan’s jouissance into heuristic correspondence with these circuits, we argue that top-down "meta-labeling" can function as a biologically relevant regulatory mechanism. Drawing on cumulative prediction errors and selfobject failure, we describe a regime of relatively unmediated interoceptive distress in which anterior-insular signals are less constrained by higher-order contextual and regulatory processes—a neurophenomenological construct we term the "Naked Insula." Finally, we propose a clinical sequencing principle for psychosomatic and pain-focused therapy: prioritizing somatic interoceptive tolerance before, or alongside, intensive narrative reconstruction.
