我们可以记录下梦境吗?

Could We Record Our Dreams?

梦是神奇的现象——考虑到你花了你一生中差不多六年的时间做梦
Dreams are amazing phenomena — and considering you spend roughly 6 years of your life dreaming,
古怪的是,我们总是脑海中闪过梦境而又很快忘记
it’s quite curious that we often brush them aside to be quickly forgotten. Night after
我们的大脑夜复一夜地工作并带给我们一些极度惊人、奇异
night our brains go to work and bring us some of the most incredible, bizarre and often
而表面上随机的想象或是故事情节但…什么是梦呢?我们能不能
seemingly random imagery and storylines. But…what are dreams? And like the many science fiction
像很多科幻小说或电影中那样记录或是理解我们在梦中所看到的呢?
stories or movies, could we ever record and figure out what we’re seeing while we’re dreaming?
你之前也许听说过有人提到“脑电波”但你是否停下来想过:
You may have heard of people referring to ‘brain waves’ before, but have you ever stopped
这些真实的波,它们…是否能携带信息?
to think: are these actual waves, and do they… carry information? Are brain waves similar
脑电波是否能近似为无线电波?答案是,可以的;脑电波和无线电波都由电磁辐射形成—
to, say, radio waves? The answer is, yes; both brain and radio waves are forms of electromagnetic
一种以光速传播的波每当你思考时
radiation — waves that travel at the speed of light. Every time you think, thousands
数千个神经元以相同频率发出波
of neurons fire at the same frequency and generate a wave. These waves oscillate at
这些波以每秒10-100次振荡无线电波,在另一方面,
around 10 to 100 cycles per second. Radio waves, on the other hand oscillate at around
每秒振荡五千万到十亿次科学家们长期运用这个现象
50…million to 1 billion times per second. Scientists have long used this phenomenon
来衡量大脑活动以及将大脑和电子仪表连接
to measure brain activity and interface the brain to electronic devices. It allows us
这让我们能看到在不同的活动中大脑的哪个部分较为活跃
to see which parts of the brain are active for different activities, and similarly which
类似地就能得知,在梦中大脑的哪个部分比较活跃很奇怪,我们仅仅了解了
parts of the brain are active during dreaming. Strange as it may seem, we still barely understand
为什么我们睡觉但我们为什么做梦呢
来自Vsauce的迈克尔做了个不可思议的研究
why we sleep let alone why we dream. Michael from Vsauce does a fantastic job explaining
解释了我们为什么做梦的主要原因但如果我们不叫醒被试者
the main theories for why we dream. But there are so many theories because we can’t really
还有很多关于他们梦境的推测我们无法衡量或得知
measure or know what people are dreaming about, without waking them up and asking them. Of
当然,这是十分容易遗忘或出错的不幸的是
course, this is subject to forgetting or other errors. Unfortunately, there is no device
还没有方法能让我们窥视做梦者的脑海…还是已经有了?
that exists to allow us to peer into the mind of a dreamer…or is there?
听起来十分疯狂但科学家们创造了一个技术来实现它
Crazy as it sounds, scientists have created a technique to do just that. This mind-reading
这项读心术来源于一个功能性核磁共振扫描仪向被试者秘密地展示一些黑白图片
technology began with a functional MRI Scanner, inside which subjects were shown simple pictures
之后软件会发现相应的大脑特定想象的模式
made up of black and white pixels. The software then finds patterns in the brain activity
例如,先给一个T字母
that corresponds to the specific images. For example, if the letter ‘T’ was shown, the
软件就会精确地记录下大脑的反应在足够的数据下

software would record exactly how the brain reacted. After sufficient data, the subjects
被试者看了完全不同的图像软件会预测并重建
were then shown completely different images, and the software would predict and recreate
它认为被试者所看到的软件探测了“神经元”之后,
what it thought the subjects were seeing. After being shown the word ‘Neuron’ these
它生成了联想但它并不止步于此—
were the images the software generated. But it doesn’t stop there — further studies
根据被试者睡觉时的更多复杂的图形研究会更进一步

began to use more complex visuals during the subjects sleep. In this case, they first had
于是,首先采用功能性磁共振成像被试者睡着,在做了一半梦时被叫醒
the subjects fall asleep while in an fMRI, and would wake them up in the middle of dreaming,
立即问他们梦了什么之后使用网络上的数千图形
quickly asking them what they were dreaming about. They then used thousands of images
来做一个最接近于被试者脑部扫描的图像
from the internet to get a best approximation of what the subject was seeing based on brain
在每个人都这样做了接近200次后将信息转化为学习算法
scans. After doing this nearly 200 times with each person, and plugging the information
让软件能用来预测和生成他们未来的梦
into a learning algorithm, software was used to predict and generate their future dreams.
虽然仍不准确但机器的预测能十分清晰地
Though by no means perfect, it was clear that the machines predictions were better than
和做梦者的描述相匹配也许更令人震惊的是
chance, matching up with the dreamers description. Perhaps even more shocking is a study that
这个研究还使用了录像片段在给被试者展示了两小时的电影片段后
actually used video footage; after showing subjects 2 hours of movie footage and analyzing
分析他们的大脑活动他们从一千八百万的文库中
their brain activity, they then used a library of 18 million, 1 second YouTube clips to match
选出一秒youtube的片段来匹配大脑活动。结果是这样的:在左边
the brain activity. Here are the results: On the left are new, unrelated clips that
给被试者展示了不相关的片段后右边的软件
the subjects were later shown, and on the right is what the software guessed they were
把youtube片段拼凑起来来猜测被试者所看到的
seeing, using a mashed up combination of the YouTube clips as an approximation. All of
这些都是以他们的脑电波为基础随着程序数量和复杂度的不断提高
this based on their brain waves. As these software programs become more and
我们能更精确地观察记录我们的想法和梦境
more complex, we come that much closer to accurately visualizing and recording our thoughts
从这个角度出发,我们能首先发现更多为什么做梦的蛛丝马迹
and dreams. At which point, perhaps, we’ll have a few more clues into why we dream, in
