《素问·脉要精微论》说:“头者,精明之腑。”“夫精明者,所以视万物,别黑白,审长短,……”很显然,“精明”应属脑神经功能活动范畴。故李时珍也说:“脑为元神之腑”其意认为人脑是思维、意识的策源地和维系生命活动的主宰器官。 “Su asked the pulse to be subtle”, said: “The first person, shrewd.” “Fast savvy, so depending on all things, not black and white, trial length, ...” Obviously, “smart” should be a brain function activity category. Therefore, Li Shizhen also said: “The brain is the soul of the gods.” It means that the human brain is the source of thinking, the source of consciousness, and the dominating organ that sustains life activities.
