Most neurons can’t divide to form new cells, so there’s no way to replace them if they die.
大多數神經細胞無法分裂產生新的細胞，因此一旦神經細胞死亡就沒有其它細胞可以替代。
But living neurons continue to grow all of our lives, forming new branches and connections with other neurons.
但是存活的神經細胞會繼續隨著人體發育不斷成長，形成新的分支并與其他神經細胞建立連接。
That makes up for much of what we’ve lost.
這就彌補了大部分損失掉了的神經細胞。
And there’s another type of brain cell, called a glial cell, that can divide to form new cells.
此外，還有一種名為神經膠質細胞的腦細胞，這種細胞會分裂并產生新的細胞。
Glial cells help neurons do their job better and provide a framework to support them.
神經膠質細胞能幫助神經元更好的完成工作并提供一個框架支持他們。
But brain power isn’t just about numbers of cells.
但是智力不僅僅取決于神經細胞的數量。
Eating a well-balanced diet and experiencing and learning new things all influence the way neurons branch and connect.
飲食均衡，感受和學習新鮮事物都會影響神經元分叉和連接的方式。
In other words, the more you use your brain, the better it works.
換句話說，大腦越用越靈活。
