[00:00:00]You take one cold bite of ice cream.

[00:00:03]The roof of your mouth gets hit first.

[00:00:05]Blood vessels clamp down, then rebound.

[00:00:08]Pain sensors fire, but the signal doesn't say mouth.

[00:00:13]It races through the trigeminal nerve, and your brain files it under forehead.

[00:00:18]That is called brain freeze, but the pain is not in your brain. It starts in your palate. Warm the roof of your mouth, and the alarm can shut off.
