A multilayered model of the self links four layers—relational alignment, self-constitution, self-manifestation, and self-expansion—to distinct neural correlates and levels of personality organization. The model proposes that psychotic, borderline, and neurotic personality organizations correspond respectively to disruptions in self-constitution, self-manifestation, and self-expansion. Grounded in empirical data on neural correlates of the self, early attachment experiences, and resting-state brain activity (rest-self overlap/containment), the model integrates psychodynamic and neuroscientific perspectives. The spontaneous activity of the brain, intrinsically related to the self, may be key to understanding how the default state navigates internal and external reality.
Dreams occupy a bizarre and poorly understood state of consciousness. The Topographic-dynamic Re-organization model (TRoD) proposes that dreaming involves a shift toward increased activity and connectivity in the default-mode network (DMN) alongside reduced activity in the central executive network, except during lucid dreaming. Dynamically, dreams shift toward slower brain frequencies and longer timescales, placing them between wakefulness and NREM stage 2 or slow-wave sleep. This re-organization produces abnormal spatiotemporal processing of internal and external inputs, moving from temporal segregation to integration. The resulting integration yields bizarre, self-centric mental content and hallucinatory-like states, suggesting that topography and temporal dynamics may serve as a common currency linking brain activity to dream experience.
