There is a railway worker named gage. He is very quiet. His employer called him the best foreman, and everyone around him respected and liked him. He has "iron willpower and physique". But in a railway blasting accident, a steel bar passed through his head and hit his forehead cortex. He's not dead. Under the doctor's treatment, he recovered and returned to work in a few months. However, great changes have taken place in his personality. He began to abuse others rudely, trying to control others. When he was restricted by others, he would lose patience, and even the rehabilitation plan formulated by the doctor could not be carried out as usual. He lost his prefrontal cortex and self-control at the same time Although we have a good prefrontal cortex, like gage, when we are drunk, lack of sleep and distracted, it will affect the prefrontal cortex. We will have the impulse to do "easy things", but in fact we have the ability to do "more difficult things".
