St. Louis, Aug. 9, 1999 -- Putting a new twist on an imaging technique,researchers now are able to identify tiny, malformed blood vessels in the brainthat usually are missed by traditional imaging tests. The results may lead tomore appropriate treatment of children and adults affected by these ra...Pain, itself, elicits pain relief, and does so through 'reward' pathway
