I recently mentioned the discovery of eleven Mesolithic skulls in Motala, Sweden. One of the skulls contained a lump of organic matter that now has been analyzed by brain researchers from Karolinska Institutet in Stockholm, one of Europe’s largest medical universities. The lump contains traces of protein which usually only is found in the brain.
The researchers are developing a diagnostic method for brain damage. Brain proteins that are so old can be good candidates for blood analysis. They are looking for proteins that usually are found in the brain, which can leak into the blood if the head is wounded, such as during a car accident. More about the method and its medical use here (in Swedish though).
