So how 'd you bump your noggin ?

那你是怎么把脑袋撞了的?

I bumped my noggin on the ground .

我的脑袋碰到地上。

What do you think goes on in that noggin of his ?

你说他的小脑袋在想什么?

With billions of neurons , each with thousands of connections , one 's noggin is a complex , and yes congested , mental freeway .

人的脑袋像是一条复杂而拥挤的精神高速公路，由无数神经元组成，每个神经元都通过数以千计的连接互联。

Leave your noggin the way it is , though .

但是，还是让你的头保持原形吧。
