Basically what we need to do is replace cells in those few areas of the brain that lose cells at a respectable rate, especially neurons, but we don't want to replace them any faster than that -- or not much faster anyway, because replacing them too fast would degrade cognitive function.
基本的に 細胞の入れ替えが必要です 脳細胞の一部分など 相当量を失うことになる 特に神経細胞は なるべく入れ替えたくない 早過ぎても 遅過ぎてもダメです 早く入れ替えれば 認知機能が落ちてしまう
