TED演讲之神奇奥秘 奥利弗·萨克斯:幻觉背后的心智(8)
Charles Bonnet said, 250 years ago — he wondered how, thinking these hallucinations, how, as he put it, the theater of the mind could be generated by the machinery of the brain.
查尔斯·邦纳在250年前在对这些幻觉现象的观察的促使下，思考了这个问题，心智的戏剧性是如何产生于大脑运作的呢？
Now, 250 years later, I think we’re beginning to glimpse how this is done. Thanks very much.
250年后的今天，我想我们已经能够开始领悟这个精妙的过程，非常感谢。
Chris Anderson: That was superb. Thank you so much. You speak about these things with so much insight and empathy for your patients.
克里斯·安德森：非常精彩，非常感谢你，你说得非常精到，也很能理解你的病人。
Have you yourself experienced any of the syndromes you write about?
你自己有没有过这些症状呢？
Oliver Sacks: I was afraid you’d ask that. Well, yeah, a lot of them.
奥利弗·萨克斯：我挺怕你问这个的，嗯，有，很大一部分。
And actually I’m a little visually impaired myself. I’m blind in one eye, and not terribly good in the other.
事实上我自己也有一定的视力受损，我的一只眼睛是看不到的，另一只视力也不大好。
And I see the geometrical hallucinations. But they stop there.
我看到过几何幻觉，不过最多也就这个程度了。
CA: And they don’t disturb you? Because you understand what’s doing it, it doesn’t make you worried?
安德森：它们会不会让你感到很不安？或者说是不是因为你了解这一现象而没这么担心？
OS: Well they don’t disturb me any more than my tinnitus, which I ignore.
萨克斯：耳鸣让我烦心得多，耳鸣我也是听而不闻。
They occasionally interest me, and I have many pictures of them in my notebooks.
不过偶尔我会对自己的幻觉很感兴趣，我还把它们画在了笔记本里。
I’ve gone and had an fMRI myself, to see how my visual cortex is taking over.
我自己就曾做过功能性磁共振成像，看看我的视觉皮层在造什么反。
And when I see all these hexagons and complex things, which I also have, in visual migraine, I wonder whether everyone sees things like this,
我看到六边形的幻觉，或更复杂的幻觉，往往伴随着偏头痛，那是我就会想是不是别人也会有这样的幻觉。
and whether things like cave art or ornamental art may have been derived from them a bit.
洞穴壁画和装饰艺术是不是也取材于这种幻觉。
CA: That was an utterly, utterly fascinating talk. Thank you so much for sharing.
安德森：你今天的演讲非常非常精彩，感谢你的分享。
OS: Thank you. Thank you.
萨克斯：谢谢，谢谢。
