人的大脑的潜力是巨大的。这种潜力一旦被普遍地发掘和利用,人的智力水平必然会大大地提前和提高一步。人脑是由140亿左右个脑细胞组成的信息贮存库。人脑神经细胞的增殖,在胎儿形成后的第二个半月至四个半月是第一次高峰,出生后的第三个月出现第二个增殖高峰,到二岁左右,便停止增殖了,也就是说,二岁左右的幼儿的脑细胞已达到成年人的数量了。就脑的平均重量而言,新生儿的脑重约380克左右,九个月约660克,二岁半到三岁可达900-1011克,七岁儿童为1280克,已接近成年人
The potential of the human brain is enormous. Once this potential has been universally exploited and utilized, the level of human intelligence is bound to be greatly advanced and advanced. The human brain is an information repository made up of about 14 billion brain cells. Proliferation of human brain cells, the first half of the month to four and a half months after the formation of the fetus is the first peak, the second peak of proliferation after the third month of birth, to two years old, they stop proliferation, In other words, young children aged two or older have reached the number of adults in their brain cells. In terms of average brain weight, the newborn's brain weighs about 380 grams, about 660 grams in nine months, 900-1011 grams at two and a half to three years of age, and 1280 grams at seven years of age, which are close to those of adults
