In studies with animals, exercise, in the form of running wheels or treadmills, has been found to double or even triple the number of new neurons that appear afterward in the animals’ hippocampus, a key area of the brain for learning and memory, compared to the brains of animals that remain sedentary. Scientists believe that exercise has similar impacts on the human hippocampus.

獨立成句；（翻譯的時候是否獨立成句是由長度決定的；

閱讀時盡量的獨立成句，這樣會讓你的理解更加精確！）

同位語獨立成句：

Hippocampus is a key area of the brain for learning and memory.

海馬正是學習和記憶的關鍵腦區

參考譯文：在動物研究中，鍛煉，比如在跑輪或跑步機上慢跑后，動物海馬新生神經元的數量可達不運動動物的兩倍甚至三倍，而海馬正是學習和記憶的關鍵腦區。

第二句：

Scientists believe that exercise has similar impacts on the human hippocampus.

科學家認為，運動對人體海馬也會產生類似的影響。
