100.With him, and with Rosalie, what seems to be going on — and Rosalie said, “What’s going on?” — and I said that as you lose vision,
这种在查尔斯·鲁林和罗斯莉 身上发生的 让罗斯莉问道“我这是这么了？”的现象 我这么解释吧：随着视力的减退
101.as the visual parts of the brain are no longer getting any input, they become hyperactive and excitable.

我前面提到过，视力受损的人 有10%会产生幻觉
135.But no more than one percent of the people acknowledge them.
但不超过1%会承认
136.Because they are afraid they will be seen as insane, or something.
因为他们担心会被当成疯子之类
137.And if they do mention them to their own doctors they may be misdiagnosed.
而如果他们向医生提起这种症状 医生可能会做出错误的诊断
138.In particular, the notion is that if you see things or hear things, you’re going mad.
而且，大家往往认为 如果你看到或听到幻觉，你就是疯了
139.But the psychotic hallucinations are quite different.
其实我们提到的这种幻觉跟精神病幻觉是不一样的
140.Psychotic hallucinations, whether they are visual or vocal, they address you. They accuse you.

145.There is a film. You’re seeing a film which has nothing to do with you.
邦纳式幻觉就像一部电影，尽管你在看，电影却没有牵涉到你
146.Or that’s how people think about it.

153.And it’s that Tuesday evening back in 1982.
那可能是1982年的某个周二夜晚
154.And the temporal lobe hallucinations are all multisensory hallucinations, full of feeling, full of familiarity, located in space and time,
这种颞叶异常导致的幻觉 是多感官的 充满着情绪和熟悉感 发生在特定时空中
155.coherent, dramatic.
情节合乎逻辑而戏剧感十足
156.The Charles Bonnet ones are quite different.
邦纳式的不一样
157.So in the Charles Bonnet hallucinations, you have all sorts of levels, from the geometrical hallucinations, the pink and blue squares the woman had,
在邦纳式幻觉中 有好几种等级 从几何幻觉 比如老太太看到的粉色和蓝色的方块
158.up to quite elaborate hallucinations with figures and especially faces.
到非常复杂的幻觉 比如各种人像，尤其是面容
159.Faces, and sometimes deformed faces, are the single commonest thing in these hallucinations.
这些面容，有时是扭曲的面容 是唯一一种在这些幻觉中 最常见的幻象
160.And one of the second commonest is cartoons.
一种第二常见的幻象是卡通
161.So, what is going on?
那么，究竟为什么会产生幻觉呢？
162.Fascinatingly, in the last few years, it’s been possible to do functional brain imagery, to do fMRI on people as they are hallucinating.
很棒的是，近几年 我们能够做出脑功能成像 当我们给正产生幻觉的人做功能性磁共振成像(fMRI)时
163.And in fact, to find that different parts of the visual brain are activated as they are hallucinating.
我们的确发现大脑视觉部位 有不同区域被激活 这时被检测者正在经历幻觉
164.When people have these simple geometrical hallucinations, the primary visual cortex is activated.
如果被检测者有的是简单的几何幻觉 被激活的区域则是初级视觉皮质
165.This is the part of the brain which perceives edges and patterns.
这是大脑感知边缘和图案的部分
166.You don’t form images with your primary visual cortex.
而我们光靠这里是无法形成完整影像的
167.When images are formed, a higher part of the visual cortex is involved in the temporal lobe.
影像形成时 一个位于颞叶的较高级视觉皮质 会有一定活动
168.And in particular, one area of the temporal lobe is called the fusiform gyrus.
尤其是颞叶中 叫做梭状回的一个区域，显著地活跃
169.And it’s known that if people have damage in the fusiform gyrus, they maybe lose the ability to recognize faces.
调查显示，如果梭状回损伤 患者可能因此无法辨认面容
170.But if there is an abnormal activity in the fusiform gyrus, they may hallucinate faces.
而当梭状回异常时 患者则可能看到面容的幻象
171.And this is exactly what you find in some of these people.
这正是我们前面提到的几位病人所出现的症状
172.There is an area in the anterior part of this gyrus where teeth and eyes are represented.
梭状回的前部有一个区域 负责处理有关牙齿和眼睛的影像
173.And that part of the gyrus is activated when people get the deformed hallucinations.
而当病人出现扭曲的幻觉时 正是这一部位出现了活动
174.There is another part of the brain which is especially activated when one sees cartoons.
还有一个区域 会在病人看到卡通幻象时 出现活动
175.It’s activated when one recognizes cartoons, when one draws cartoons, and when one hallucinates them.
人们观看卡通 画卡通，或看到卡通幻象时，都是这一部位被激活
176.It’s very interesting that that should be specific.
这是一个特别有趣的现象
177.There are other parts of the brain which are specifically involved with the recognition and hallucination of buildings and landscapes.
大脑还有几个别的部位 相应地跟其他视觉元素的辨别与幻觉有关 比如楼房和风景
178.Around 1970 it was found that there were not only particular parts of the brain [involved], but particular cells.
1970年左右，人们发现特化的不是一块区域 而是相应的脑细胞
179.”Face cells” were discovered around 1970.
“脸细胞”是1970年左右发现的
180.And now we know that there are hundreds of other sorts of cells, which can be very very specific.
至今，我们已经发现了 数百种与各类视觉元素对应的脑细胞 这种对应关系可以非常琐细、明确
181.So you may not only have “car” cells, you may have “Aston Martin” cells.
比如说 “车”细胞 可能还有“阿斯顿·马丁(一种车)”细胞
182.(Laughter) I saw an Aston Martin this morning.
(笑声) 今早我看到一部阿斯顿·马丁
183.I had to bring it in.
我一直想提提它
184.And now it’s in there somewhere.
现在我的脑子里就有这种“阿斯顿·马丁”细胞
185.(Laughter) Now, at this level, in what’s called the inferotemporal cortex, there are only visual images, or figments or fragments.
(笑声) 那么，这一程度的幻觉，只会由这一整块可以称作下颞叶皮质的区域 形成视觉影像、 幻象，或片段
186.It’s only at higher levels that the other senses join in and there are connections with memory and emotion.
只有更高程度的幻觉 才会有视觉以外的感官参与 同时牵涉到记忆与情感
187.And in the Charles Bonnet syndrome you don’t go to those higher levels.
在邦纳症候群中 更高程度的幻觉并不会出现
188.You’re in these levels of inferior visual cortex where you have thousands and tens of thousands and millions of images, or figments, or fragmentary figments,
牵涉到初级视觉皮质的幻觉 有上百上千 甚至更多的图像、 幻象，或残缺幻象
189.all neurally encoded, in particular cells or small clusters of cells.
这些都被编译 在特定的脑细胞或脑细胞簇中
190.Normally these are all part of the integrated stream of perception, or imagination.
这些细胞通常 参与形成感知和想象
191.And one is not conscious of them.
人们通常是无法意识到这一过程的
192.It is only if one is visually impaired, or blind, that the process is interrupted.
只有当你的视力受损或丧失 这一过程才会被干扰
193.And instead of getting normal perception, you’re getting an anarchic, convulsive stimulation, or release, of all of these visual cells,
在这种情况下，你的感知不再正常 一种不受控的、 痉挛的释放活动 发生在位于初级视觉皮质的
194.in the inferotemporal cortex.
这些视觉脑细胞中
195.So, suddenly you see a face. Suddenly you see a car.
这种活动的结果就是，你突然看到一张脸，转瞬看到一辆车
196.Suddenly this, and suddenly that.
突然这，突然那
197.The mind does its best to organize, and to give some sort of coherence to this.
大脑会尝试控制场面 尝试使这一切符合逻辑
198.But not terribly successfully.
但不会很成功
199.When these were first described it was thought that they could be interpreted like dreams.
这些现象最初被描述时 人们相信，跟梦一样，这种幻觉也能被强行中止
200.But in fact people say, “I don’t recognize the people. I can’t form any associations.”
不过实际上患者表示 “我认不出来谁是谁。完全没办法想到任何信息。”
201.”Kermit means nothing to me.”
”青蛙柯密特对我来说一点意义都没有啊。“
202.You don’t get anywhere thinking of them as dreams.
把这种现象视作梦的一种是行不通的
203.Well, I’ve more or less said what I wanted.
唔，我应该说得差不多了
204.I think I just want to recapitulate and say this is common.
我再概括一下 其实帮纳症候群是个常见现象
205.Think of the number of blind people.
你们想，在盲人人群中
206.There must be hundreds of thousands of blind people who have these hallucinations, but are too scared to mention them.
肯定有上百上千 有这样的幻觉 然而却不敢提起
207.So this sort of thing needs to be brought into notice, for patients, for doctors, for the public.
所以不管是病人，医生还是公众 都有必要认识到这一现象的常见性
208.Finally, I think they are infinitely interesting, and valuable, for giving one some insight as to how the brain works.
最后 我发现帮助别人认识大脑作用的原理 是一件无比有趣而有意义的事情
209.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？
210.Now, 250 years later, I think we’re beginning to glimpse how this is done.
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
211.Thanks very much.
非常感谢
212.(Applause) Chris Anderson: That was superb. Thank you so much.
(掌声) 克里斯·安德森：非常精彩，非常感谢你
213.You speak about these things with so much insight and empathy for your patients.
你说得非常精到 也很能理解你的病人
214.Have you yourself experienced any of the syndromes you write about?
你自己有没有过这些症状呢？
215.Oliver Sacks: I was afraid you’d ask that.
奥利弗·萨克斯：我挺怕你问这个的
216.(Laughter) Well, yeah, a lot of them.
(笑声) 嗯，有，很大一部分
217.And actually I’m a little visually impaired myself.
事实上我自己也有一定的视力受损
218.I’m blind in one eye, and not terribly good in the other.
我的一只眼睛是看不到的，另一只视力也不大好
219.And I see the geometrical hallucinations.
我看到过几何幻觉
220.But they stop there.
不过最多也就这个程度了
221.C.A.: And they don’t disturb you?
安德森：它们会不会让你感到很不安？
222.Because you understand what’s doing it. It doesn’t make you worried?
或者说是不是因为你了解这一现象而没这么担心？
