近日,《美国医学协会杂志》刊登了一项最新研究,发现长寿老年人大脑中“皮质层”厚度是普通老年人的两倍;皮质层越厚,大脑衰老速度越慢。研究人员认为,了解长寿者的大脑秘密有利于我们维护健康、延年益寿。研究指出,大脑皮质层就像一张被揉皱的报纸,伸展后的面积和厚度决定着脑容量。皮质层厚说明认知、理解、记忆、判断、计算、语言等高级神经功能好。研究对象中有一位89岁的美国老人唐纳德,他因为皮质层厚而 Recently, the Journal of the American Medical Association published a new study, found that longevity elderly brain “cortex” thickness is twice the thickness of the elderly; cortical thicker, slower brain aging. Researchers believe that understanding the secrets of the longevity of the brain will help us maintain our health and live longer. Studies show that the cerebral cortex is like a crumpled newspaper, stretching the area and thickness determines the brain capacity. Cortical thick cognitive, understanding, memory, judgment, calculation, language and other advanced neurological function is good. The research object is an 89-year-old American old Donald, who because of the cortical thickness
