The Neural Signature of Self-Referential Integration: How mPFC-PCC Circuits Transform Information into Subjective Experience (Internalization Theory)

Consciousness science has characterized how information becomes globally accessible and integrated, yet a fundamental question remains: why do conscious experiences feel distinctly "mine"? This phenomenal ownership the subjective quality distinguishing awareness from unconscious processing represents the ownership gap in consciousness research. Here we propose that ownership emerges through self-referential integration, whereby medial prefrontal-posterior cingulate (mPFC-PCC) circuits incorporate information into a distributed self-model via theta-gamma phase-amplitude coupling. Drawing on cultural neuroscience showing how different self-construals produce distinct neural patterns, our framework explains both universal mechanisms and cultural variation. We operationalize consciousness through triangulated criteria neural connectivity, behavioral self-prioritization, and phenomenological ratings enabling empirical validation. The framework generates specific predictions including a critical test: transcranial magnetic stimulation to mPFC-PCC should preserve detection while abolishing ownership, a dissociation no competing theory predicts. Crucially, we demonstrate that self-referential integration logically dissolves the classical philosophical problems hard problem, zombie argument, knowledge argument, and inverted spectrum through necessary conceptual analysis. We present clinical applications for PTSD, depression, and disorders of consciousness diagnosis.
