See, understanding where the brain begins and ends is part of understanding well the brain.

理解大脑的起点和终点是理解大脑的一部分。

And even though there's no one perfect definition for our brains, asking where our brains start and end can help us understand how they interact with our bodies and help us do everything we do.

尽管我们的大脑没有一个完美的定义，但研究大脑的构成可以帮助我们理解它们是如何与我们的身体相互作用的，并帮助我们做我们所做的一切。
