【双语有声阅读】为什么会怕痒(2)

The part of the brain that is associated with tickling¹ is the cerebellum. It monitors our movements, but ignores movements not perceived as a threat. For example, we do not notice our vocal² chords moving when we speak, but we may jump if someone touches us on the shoulder. This selective perception is probably the reason why we cannot tickle³ ourselves.

 

脑部与怕痒有关的部位是小脑。小脑监控我们的一举一动，但对其认为不具威胁性的活动，往往会忽视。举例来说，我们说话时不会察觉声带的振动，但是如有人触摸我们的肩膀时，我们可能会吓一跳。这种选择性的知觉或许就是我们无法自己哈痒的原因。
