有学者把大脑比喻为头颅内的银河系,这符合“人与天地相应”学说。浩如烟海的银河系大约有140亿个星球,大脑的神经细胞也是140亿个左右;银河系呈穹窿形,大脑皮质也是穹窿形,紧紧附在脑实质的表面。每一个神经细胞就像一个星球。人类对银河系的内幕了解得不多,对自己头脑中的大脑皮质了解得也很少。有学者把大脑比喻为超高级大型计算机组。计算机分为数学计算机和模拟计算机两大类,人脑则同时兼具两者的功能。神经细胞的每个细胞核中的原生质相当于超大型集成电
Some scholars compared the brain to the intracranial Milky Way, which is consistent with the “people and world corresponding” doctrine. There are about 14 billion planets of vast galaxies and about 14 billion nerve cells in the brain. The Milky Way is a dome-shaped, the cerebral cortex is also a dome-shaped, tightly attached to the surface of the brain parenchyma. Every nerve cell is like a planet. Humans know little about the inside story of the Milky Way and do not know much about the cerebral cortex in their minds. Some scholars compare the brain to a supercomputer group. Computer is divided into two major categories of mathematical computer and analog computer, while the human brain combines the functions of both. The protoplasm in each nucleus of nerve cells is equivalent to very large integrated circuits
