A map of brain regions associated with language processing in the human cerebral cortex. Yellow and red regions are activated by listening to stories, whereas green and blue regions are more strongly activated by doing mathematical calculations.
If it hasn't happened to you, count yourself as lucky. For many people, eating ice cream or drinking an icy drink too fast can produce a really painful headache. It usually hits in the front of the brain, behind the forehead.
The technical name for this phenomenon is cold-stimulus headache, but people also refer to it as "ice cream headache" or "brain freeze."
The good news is that brain freeze is easy to prevent — just eat more slowly. The other bit of good news is these headaches don't last very long — a minute at the outside.
