人类的大脑是一个了不起的东西。
It can do things our primate relatives are thousands- maybe even millions - of years of evolution awayfrom, and our most complex machines are not evenclose to competing with our powers of higherconsciousness and ingenuity.
人脑能完成未经历上千年，甚至也许是数百万年进化的灵长类亲戚不能完成的事情。并且我们最复杂的机器都远远不能与我们的高等意识和创造力竞争。
And, oddly enough, even without any injuries orstructural malfunctions, the human brain can get weird all by itself - turns out, it's surprisinglyeasy to trick it into seeing and hearing things that aren't actually there.
而且，奇怪的是，即使没有任何损伤或结构故障，人脑本身也会变得很奇怪——事实证明，让它看到和听到实际上不存在的东西是非常容易的。
As demonstrated by the guys in this 2016 Scam Nation video on YouTube, if you create asituation of intense sensory deprivation using some common household objects, you caninduce some really strong hallucinations that mess with both your sense of sight and sound.
就像YouTube网上2016“诈骗国家”中的那些家伙展示的那样，如果你用常见的家庭用品制造一个强烈的视觉剥夺环境，那你可以引发一些十分强烈的幻觉，欺骗你的视觉和听觉。
You're going to need:
你需要：
Sheets of light, white paper
一张张白纸
Cotton padding
棉花衬垫
Rubber bands
橡皮筋
Stationery, including scissors, tape, a stapler, and string
文具，包括剪刀、胶带、订书机和绳子
A YouTube video of old television white noise or static that runs uninterrupted for at least 30 minutes
一段YouTube上的旧电视白噪音或静电的视频，至少不间断地播放30分钟
Noise-cancelling headphones
降噪耳机
The effects usually start to show after about 10 to 30 minutes.
效果通常在10到30分钟后开始显现。
After 20 minutes, the Scam Nation guys reported seeing "blooms of colour" - like those yousee when you rub your eyelids - that would soon form shapes, such as dinosaur silhouettes, jellyfish, and the Eye of Sauron.
20分钟后，“骗子国度”的人报告说，他们看到了“色彩斑斓的花朵”——就像你揉眼睑时看到的那样——很快就会形成各种形状，比如恐龙的轮廓、水母和索伦的眼睛。
One heard screams, and the other heard laughter.
一个听到尖叫声，另一个听到笑声。
Sounds like nonsense? Well, sure, we have to take the word of two dudes on YouTube for thisparticular scenario, but what they're doing actually follows the principles of a scientificphenomenon known as the Ganzfeld effect.
听起来像胡说八道?当然，在这种特定的情况下，我们必须承认YouTube上两个家伙的话，但是他们所做的实际上是遵循了一种科学原理，即甘兹菲尔德效应。
The Ganzfeld effect describes how when you're exposed to "an unstructured, uniformstimulation field" - such as seeing blackness and hearing constant television static - yourbrain responds by amplifying neural noise in an effort to find missing visual signals.
甘兹菲尔德效应描述了当你置身于“一个非结构的、均匀的刺激场”时，你的大脑如何通过放大神经噪声来寻找缺失的视觉信号。
This can result in both visual and aural hallucinations like the guys in the video describe.
这会导致视觉和听觉上的幻觉，就像视频中描述的那样。
Of course, every person will experience the effect in different ways.
当然，每个人都会以不同的方式体验这种效果。
