长期以来,绝大多数的神经生物学家认为哺乳动物中枢神经系统的神经细胞在行将出生前或出生后便失去了再生的能力。然而最新的一项研究表明,一种天然产生的蛋白质能促使成年小鼠脑神经细胞的生长与分裂。这一发现使得许多神经学家大为震惊。这无疑也提示哺乳动物中枢神经系统在受外伤或疾病之 For a long time, the vast majority of neurobiologists believe that nerve cells in the mammalian central nervous system lose their ability to regenerate before or after they are born. However, a new study shows that a naturally occurring protein can promote the growth and division of brain cells in adult mice. This discovery has alarmed many neuroscientists. This undoubtedly also suggests that the mammalian central nervous system is undergoing trauma or disease
