Meaning that the urge to scratch an itch begins as soon as serotonin leaves your brain and reaches the irritated spot, so whenever we scratch an itch we're actually doing so because the pain of scratching temporarily overrides the itchy feeling.
這代表一旦血清素離開大腦到達患部,你就會產生抓癢的欲望。所以我們在抓癢時就是這麼回事,因為抓癢造成的疼痛感會覆蓋過癢的感覺。
