Itchy neurons fingered

Neurons involved in pain processing have been the subject of much research in the past decades, but neurons responsible for a more pesky problem -- itchy skin -- remain elusive. In fact, many neurons seem to be involved in itch response, a process closely linked to the processing of pain in the brain, researchers reported today at the linkurl:annual meeting of the Society for Neuroscience,;http://www.sfn.org/am2008/ in Washington, D.C. To find which neurons were responsible for the itching res
