We all enjoy a nice bowl of ice cream until the brain freeze sets in but what exactly is brain freeze? The mouths palate contains many little blood vessels called capillaries and a bunch of nerve fibers called nociceptors which can detect painful or noxious stimuli. The ice cream causes the capillaries in the roof of the mouth to constrict so quickly that the nociceptors send a signal of pain to the brain. To lessen the effects David Niesel and Norbert Herzog recommend drinking warm water or pushing your tongue against the roof of your mouth.
