Abstract
One of the dogmas of neurobiology has it that when nerve cells in the vertebrate brain die, they are not replaced by new ones. The author finds to the contrary. He has shown that when the adult canary needs to learn new songs, it does grow some new neurons. The finding could eventually lead to the discovery of ways to repair lesions in the human brain.
摘要
神经生物学的一个教条是，脊椎动物大脑中的神经细胞死亡后，不会有新的细胞替代它们。作者却发现事实并非如此。他已经证明，成年金丝雀在需要学习新歌时，确实会生长出一些新的神经元。这一发现最终可能会带来修复人类大脑损伤方法的发现。
