- So one thing that I do agree with, and I think most experts would, is that the brain does have these dynamics.
- 其中一点我个人是同意的，我相信绝大多数专家也同意，那就是脑部确实有这样的动态。
- It does lag behind the skull and then catch up and move back and forth and oscillate. That we think is true.
- 它的运动迟于颅骨，接着逐渐追赶上，并向前向后振动，这一点上我们认为它是正确的。
- However, the amount of motion you see in the brain in this video is probably not right at all.
- 然而，视频中所示的脑部的运动大小，可能并不准确。
- There's very little room in the cranial vault, only a few millimeters,
- 颅顶的空间极小，只有几微米，
- and it's filled entirely with cerebral spinal fluid, which acts as a protective layer.
- 同时这些空间填满了脑脊液，这些脑脊液对脑部来说是一个保护层。
- And so the brain as a whole probably moves very little inside the skull.
- 所以说，整体来看，脑部在颅骨内的移动极为微小。
- The other problem with this video is that the brain is shown as a kind of rigid whole as it moves around, and that's not true either.
- 视频中还有另外一个问题，视频中所示的脑部，在它移动时像是一个坚硬体，这也是错的。
- Your brain is one of the softest substances in your body, and you can think of it kind of like jello.
- 人类的大脑是人体上最柔软的物质之一，你可以把它想象成果冻。
- So as your head is moving back and forth, your brain is twisting and turning and contorting, and the tissue is getting stretched.
- 所以当头部前后晃动时，脑部在旋转、扭曲，部分组织会被拉抻。
- And so most experts, I think, would agree that
- 我认为绝大多数专家都会同意这样一个观点，
- concussion is not likely to be something that's happening on this outer surface of the brain,
- 脑震荡可能不是发生在脑部的外部边缘，
- but rather it's something that's much deeper towards the center of the brain.
- 而是发生在脑部的深处，接近脑部中央的位置。
