Rather than an attempt to create an X-men-like mutation, the study sheds light on how the nervous system transmits sensory information from the body to the brain and may help to develop more sophisticated pain medicines. The study was published in the February 13 issue of the Journal of Neuroscience — led by David McKemy, associate professor of neurobiology at the University of Southern California Dornsife College of Letters, Arts and Sciences."
