Your pain is not invisible

( There is a lovely picture on the link!)

Pain, considered to be subjective and without objective measurement, is being demystified by the use of brain imaging. Oral health researchers at King's College London Dental Institute have shown with a small study that pain can be seen in the brain.

According to the New Scientist, international science and technology site and magazine, Tara Renton, professor of oral surgery at King's College London Dental Institute, "has used an alternative way of analyzing fMRI [functional magnetic resonance imaging] scans called arterial spin labeling (ASL) to measure how much oxygenated blood is flowing through particular areas."

"The definition of pain is that it is subjective, and until now an objective measurement has remained elusive," said Morten Kringelbach, author and neuroscientist at the Oxford Univeristy, to the New Scientist.
