As oxygen drops, neurons fire in chaotic, high-frequency waves — a process called terminal spreading depolarization, the brain’s last attempt to hold its electrical balance together. 2. For a brief window, activity can even surge beyond normal levels, producing synchronized gamma waves — the same patterns tied to deep memory retrieval, dreaming, and heightened awareness. It’s as if the brain scans
