Why does ice cream give us brain freeze? 

"There's a scientific medical term for ice cream headaches which is sphenopalatine ganglion neuralgia," says Dr. Kris Rau of the University of Louisville in Kentucky

"On the roof of your mouth there are a lot of little blood vessels, capillaries," Rau says. "And there's a lot of nerve fibers called nociceptors that detect painful or noxious stimuli." The rush of cold causes those vessels to constrict."And when that happens, it happens so quickly that all of those little pain fibers in the roof of your mouth — they interpret that as being a painful stimulus," Rau says.
