大脑也会重复着人间的规律,说你行你就行,说你不行你就不行。在日常生活中,常能听到某些老年人,甚至是中年人感叹到:“老了,脑子不管用了。”的确,人到一定的年龄,智力发展就会停止,这是因为随着年龄的增长,神经细胞开始萎缩,数目减少,脑重量减轻。据研究,人脑的神经细胞在18～20岁后逐渐减少,过了60岁就更加明显。人的大脑皮层细胞,每年失去成年期的0.8％,60岁时失去将近一半。有人估计,成人的大脑细胞每年死亡约
The brain will repeat the laws of the world, that you can do it on your line, that you can not do not work. In daily life, you can often hear some seniors and even middle-aged people sigh: “It’s old, it does not matter.” Indeed, when people reach a certain age, their intellectual development will stop, because With age, nerve cells begin to shrink, the number decreases, and brain weight decreases. According to the study, the human brain nerve cells gradually decreased after 18 to 20 years of age, after 60 years of age is even more obvious. Human cerebral cortical cells, each year lost 0.8% of adulthood, lost nearly half of the age of 60. It is estimated that adult brain cells die about annually
