人们常说:“心灵手巧”。这是指人的脑与手之间有着密切的关系。科学研究证明:手的活动和手指精细灵巧的动作可以刺激脑髓中的手指运动中抠,同时大脑的运动中枢又能调节手指的活动。神经中枢和手指反复地相互作用,能促进大脑的发育。因为人体的不同部位在大脑皮层上均占有一个相应的运动区,其大小不以身体部位大小而定,而是与身体部位的精细复杂程度有关。例如,人的大姆指在大脑皮层上占有的
People often say: “Ingenuity ”. This means that there is a close relationship between the human brain and the hand. Scientific research shows that hand movements and delicate movements of the fingers can stimulate the movement of fingers in the brain, while the movement center of the brain can regulate the movement of the fingers. Nerve center and fingers repeatedly interact, can promote brain development. Because different parts of the human body have a corresponding motor area in the cerebral cortex, its size does not depend on the size of the body part, but rather on the complexity of the body parts. For example, a human thumb means that it occupies the cerebral cortex
