Scientist have shown that "scratching helps relieve an itch as it blocks activity in some spinal cord nerve cells that transmit the sensation to the brain."
"The latest work, in primates, found that scratching the skin blocks activity of nerve cells in the spinothalamic tract during itchiness - preventing the spinal cord from transmitting signals from the scratched area of skin to the brain."
