一位医生,在战争中为了抢救伤病员一连紧张地奋战了几天几夜,好不容易安排他睡了觉。突然,从前线又运来了一批伤病员,需要立即叫醒这个医生。可是,不管人们用手推他,还是往他脸上喷水,都难以叫醒他。这时,一个卫生员在医生的枕边轻轻唤道;“医生,伤员到了,快醒来吧。”医生便立刻醒来,又去抢救伤病员了。这是什么道理呢?原来,人在酣睡期间,抑制便扩散到整个大脑皮层,但其中有某个不受抑制并处于兴奋的部位称为“警戒点”。通过这个警戒点,睡着的人就可以保持与外面的联系。 A doctor, in the war in order to save the sick and wounded a few days and nights fighting nervously, finally arranged for him to sleep. Suddenly, a group of wounded and sick people were brought in from the front and need to wake up the doctor immediately. However, it is hard to wake him up whether people push him by hand or spray water on his face. At this moment, a hygienist shouted gently at the doctor’s pillow: “The doctor, the wounded, wake up soon.” The doctor immediately woke up and went to rescue the wounded and sick. What is the rationale? It turned out that during sleep, people spread the inhibition throughout the cerebral cortex, but some of them are unchecked and excited parts called “points of caution.” Through this watchpoint, the sleeping person can keep in touch with the outside.
