The portion of the skull enclosing the brain; the braincase.

头颅，颅囊括脑子的那部分颅骨；脑壳。

Stranger still, the braincase was little bigger than a walnut.

更为奇怪的是，大脑甚至比胡桃还要小。

Along with bigger teeth and a studier body, the dire wolf also had a smaller braincase.

这种古狼与现代的灰狼相比，具有相对宽而短的头部，脑壳较小，同时它的牙齿也更大，身体更为健壮结实。

And when you speak, the rapid fluttering of your vocal chords actually causes your entire braincase to vibrate.

当你说话的时候，声带的快速振动带动脑壳振动。

"That's when the tiny braincase started to make sense, because early whales have big skulls and relatively small brains," Gingerich remembers.

“那时，小脑开始有意义了，因为早期鲸头骨比较大，而大脑相对小点，”金格里奇回忆说。
