“It’s possible that scratching may suppress the emotional components of itch and bring about relief,” Yosipovitch said.

Scratching increased activity in the secondary somatosensory cortex, a pain center, and in the prefrontal cortex, which is linked with compulsive behavior.
“This could explain the compulsion to continue scratching,” Yosipovitch said.
