Researchers did find a way, however, for people to tickle themselves. When volunteers activated a robot by remote control to tickle them after a short delay, the volunteers felt as if someone else were tickling them. It seems that the cerebellum sends a signal to disregard the forthcoming movement, then moves on to other things. Your brain "forgets" that you are tickling yourself—even with a delay as short as a fifth of a second. So it is possible to tickle yourself—but only by remote control. What will science discover next?

然而，研究人員也發現了可以替自己哈癢的方法。自愿者用遙控器操縱機器人，延遲片刻之后再讓機器人為自己哈癢，自愿者就會覺得好像是別人在給他們哈癢。看來小腦在發出信號忽視即將到來的動作，然后將注意力轉移到其它事物上。盡管只有零點二秒的時間差，腦部就會“忘記”你在替自己哈癢。所以自己給自己哈癢仍有可能，只不過需要依靠遙控器。誰知道接下來科學還會有什么新發現呢？
