“In experiments carried by a researchers at the National University of Ireland in Galway and Harvard Medical School a team of 13 healthy volunteers deliberately induced the brain freeze so the effects could be studied. It was found that the pain was brought on by a rapid increase in blood flow through a major blood vessel in the brain, the anterior cerebral artery. The ache subsided again once blood flow was restricted. The findings were presented at the meeting Experimental Biology 2012 being in San Diego.” w/ photo
