Mysterious Itch Cells Found
Tia Ghose, LiveScience:
Certain nerve cells are specialized to detect itchy sensations, and those receptors don’t detect painful sensations, according to a new study.
The finding, published Dec. 23 in the journal Nature Neuroscience, helps resolve a long-standing debate over whether itchiness is just a weird form of pain. Additionally, now that they have pinpointed the responsible nerve fibers, researchers could silence those nerves to develop better anti-itch treatments, said Ethan Lerner, a neuroscientist at Harvard University who was not involved in the study.
Bodies are weird.
