This can occur when you quickly eat or drink something cold. However, your brain does not actually freeze. In the roof of your mouth there are lots of very sensitive nerves that protect your brain. When these nerves feel something cold like ice cream or a frozen drink, they think the brain is too cold and automatically send messages to the brain telling it to “warm up.” In order to get warm, blood vessels in the brain dilate, or swell. This causes the painful sensation that lasts about 30 to 50 seconds.

The top of your mouth has really short and sensitive nerves to your brain. If you eat/drink too fast, usually, the cold stuff will touch those nerves and "freeze" your brain.

Because the body is 98.6 degrees, and we introduce something frozen to it. It's a shock, like throwing ice in a glass of hot water - it snaps. Our heads aren't any different - thermal shock is the technical term.

They have done research and still do not know why. There are theories, but nothing certain.
