[00:00:00]When you count backwards on the operating table, your brain doesn't simply fall asleep. Within [music] 10 seconds, anesthetic chemicals travel through your bloodstream and directly invade your cerebral cortex. These gases lock onto your neurons, instantly slowing down billions of electrical signals.

[00:00:14]>> [music] >> Next, the main communication networks in your brain stem are physically blocked.

[00:00:18]Thus, when the scalpel cuts your skin, pain signals cannot travel up your spinal cord. At the same time, your mind fractures and different brain regions stop communicating entirely. During an average 45-minute surgery, your memory center is completely shut down. Only the primitive brain centers running your heart and lungs remain active. Your core temperature drops to 95° and a mechanical ventilator takes over your breathing. When the chemical flow stops, neurons slowly wake from this artificial paralysis to rebuild connections. This is why anesthesia is never just a sleep, but a carefully controlled temporary coma.
