Scratching the surface of how your brain senses an itch

Researchers identified a set of neurons in the spinal cord that transmits a light-touch signal from the skin to the brain. NPY-Y1 signaling regulates the transmission of innocuous tactile information by establishing thresholds for touch discrimination and mechanical itch reflexes. The findings shed new light on the neurobiological basis of chronic itching.
