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(fā)現(xiàn)了可以替自己哈癢的方法。自愿者用遙控器操縱機(jī)器人，延遲片刻之后再讓機(jī)器人為自己哈癢，自愿者就會(huì)覺(jué)得好像是別人在給他們哈癢?？磥?lái)小腦在發(fā)出信號(hào)忽視即將到來(lái)的動(dòng)作，然后將注意力轉(zhuǎn)移到其它事物上。盡管只有零點(diǎn)二秒的時(shí)間差，腦部就會(huì)“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(guò)需要依靠遙控器。誰(shuí)知道接下來(lái)科學(xué)還會(huì)有什么新發(fā)現(xiàn)呢？
