Source: WikipediaFurther clues on how to tackle itch come from brain imaging studies. Many brain areas activated by pain are also active during itch, but one area that seems distinctively responsive to itch is the precuneus. This brain region is involved in visual processing and memory, says Gil Yosipovitch at the University of Miami, Florida. “We can’t pinpoint what the precuneus does in itch, but it’s uniquely activated with itch and not pain,” he says.
