Beneficial Brain Freeze?

According to a UPI article, "brain freeze" (like the kind you get when eating a cold beverage or dessert too quickly) may lead to potential migraine headache therapies. Researchers at the National University of Ireland and Harvard Medical School induced common brain freeze pain in 13 healthy volunteers so the effects could be studied.  They 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, and subsided again once blood flow was restricted.  Therefore, the thought is that blood flow control techniques might be devised to treat migraines in a similar fashion.
