A study published in the current online issue of the journal Pain found that variations in the structure of the brain are related to individual differences in pain perception. The brain is made up of both grey and white matter. Grey matter processes information much like a computer, while white matter coordinates communications between the different regions of the brain. Researchers found correlations between the amount of grey matter in certain regions of the brain and pain sensitivity. A better understanding of these structural differences may facilitate the development of better tools for the diagnosis, classification, and treatment of pain. Read a news report here.
