一项新的研究证明,保持合理饮食可提高记忆力。以色列科学家把大脑中的“树突棘”细胞分离出来,放在培养器皿里,在没有任何刺激的情况下,这些细胞能保持静止3～4小时,但当在培养液里加上咖啡因后,“树突棘”细胞不但在体积上增大,甚至出现罕见的新的分支。这说明这些细胞的功能增强了,因为“树突 A new study shows that maintaining a reasonable diet can improve memory. Israeli scientists separated the “dendritic spine” cells in their brains and placed them in culture vessels. Without any stimulation, these cells remained still for 3-4 hours, but when caffeine was added to the culture broth, “Dendritic spine” cells not only increased in size, even rare new branches. This shows that the function of these cells is enhanced because of “dendrites.”
