CONCEPT
The Override
The ancient neurological mechanism by which the brain suppresses the body's distress signals under emergency demand — adaptive when brief, catastrophic when sustained past the timescales evolution designed it for.
The override mechanism is the neurological process by which cortical, subcortical, and endocrine systems — the HPA axis, the endogenous opioid system, descending pain-modulatory pathways — suppress the body's distress signals when the demands of the situation exceed normal tolerance. The mother lifting the car. The soldier fighting on a shattered femur. The marathon runner crossing the finish line on feet she cannot yet feel. The mechanism predates human consciousness by hundreds of millions of years because the vertebrates that possessed it survived emergencies that those without it did not. The override is adaptive under one condition — brevity — and maladaptive under its opposite. What saved the organism in the short term degrades it in the long term, and the degradation is invisible for precisely the reason the mechanism exists: the signals that would report the damage are the signals being suppressed.
