New science shows exactly what is happening in your brain and how it can unlock a key to your consciousness.

新的科學顯示了你的大腦中到底發生了什麼，以及它如何打開你意識的鑰匙。

Scientists have administered psychedelics to volunteers and scan their brain using functional magnetic resonance imaging and Magneto and Cephalon graffiti and found decreased blood flow to the default mode network.

科學家給志願者注射了迷幻藥，並使用功能磁共振成像和磁鐵和頭孢塗鴉掃描他們的大腦，發現默認模式網絡的血流量減少。

The default Mode network is made up of the medial prefrontal cortex, the posterior singular cortex, the inferior parietal lobe.

默認的Mode網絡是由內側前額葉皮層、後奇異皮層、下頂葉組成。

You'll the lateral temporal cortex, the dorsal medial prefrontal cortex and the hippocampal formation.

你會外側顳葉皮層，背內側前額葉皮層和海馬形成。

This network keeps your brain working efficiently.

這個網絡能讓你的大腦高效工作。

It's evolved to filter out the vast amount of information coming to your brain by predicting what you need and getting rid of what you don't.

它的進化是通過預測你需要的東西和擺脫你不需要的東西來過濾掉進入你大腦的大量資訊。

If you are met with a new situation, your default mode network will use past experiences to make quick decisions.

如果你遇到了新的情況，你的默認模式網絡會利用過去的經驗來快速做出決定。

Using less energy.

使用較少的能源；

It creates the human capacity for self reflection, planning the future, worrying and reason it is where the brain creates the story of who you are as an individual.

它創造了人類自我反思、規劃未來、憂慮和理性的能力，它是大腦創造你作為一個個體的故事的地方。

Common psychedelics, such as Silas in or lysergic acid di ethyl amid are all trip to means.

常見的迷幻藥，如西拉斯在或麥角酸二乙胺都是行程手段。

So is serotonin, which is found naturally in your body.

血清素也是如此，它在你的身體中自然存在。

These are organic compounds with a ring of six atoms attached to another with five atoms, which all have a high affinity for a receptor found in the outermost layer of your brain, called the five ht to a receptor.

這些都是有機化合物，一個環狀的六個原子連接到另一個有五個原子，它們都有一個高親和力的受體發現在你的大腦的最外層，稱為五ht到一個受體。

Here we have the serotonin in your body, and here we have LSD.

這裡有你體內的血清素，這裡有LSD。

The trip to mean core scaffold of the LSD molecule is similar to that of the serotonin in your body.

LSD分子的旅行平均核心支架與你體內的血清素相似。

It is attached to an ERG Align scaffold connected to a di ethyl amid substitution.

它連接到一個連接到二乙基酰胺取代的ERG Align腳手架上。

Here, we see because of its similar shape to serotonin, the LSD molecule binding to your five HT to a receptor, and due to its chemical composition, it will bind for longer than serotonin ever would.

在這裡，我們看到，因為它的形狀類似於血清素，LSD分子結合到你的五個HT到受體，並由於其化學成分，它將結合更長的時間比血清素永遠不會。

Naturally in your body, when psychedelics bind to the five ht to a receptor, a cascade of cellular biology causes the default mode network to decrease.

自然地在你的身體裡，當迷幻藥與五ht結合到受體上時，細胞生物學的級聯會導致默認模式網絡減少。

This leads to ego dissolution, a k a feeling less separation from others and from nature itself.

這將導致自我消解，a k一種感覺，減少與他人和自然本身的分離。

In fact, f m r I scans of those on psychedelics is similar to experience meditators who can effectively turn off their default mode network and temporarily vanish their ego.

事實上，f m r I掃描那些在迷幻藥上的人是類似於經驗冥想者，他們可以有效地關閉他們的默認模式網絡，暫時消失他們的自我。

Other times when the default mode network is decreased is during deep prayer overwhelming experiences of off, for example, looking at the Grand Canyon or even near death experiences.

其他時候，當默認模式網絡減少的時候，是在深層的祈禱中不知所措的體驗關，例如，看大峽谷，甚至瀕臨死亡的體驗。

A decrease in the default mode network can come with hallucinations.

默認模式網絡的減少會出現幻覺。

But why on the left is a visual depiction of the neural networks in the brain of someone given a placebo pill.

但是，為什麼左邊是一個人的大腦中的神經網絡的視覺描繪，給一個安慰劑藥丸。

On the right is a visual depiction of the neural networks in the brain of someone tripping on psilocybin.

右邊是有人被psilocybin絆倒後大腦中的神經網絡的直觀描述。

With decrease action from the default mode network, your brain is no longer working efficiently.

隨著默認模式網絡動作的減少，你的大腦不再高效工作。

It now has to make sense of increased information and starts filling in the blanks with hallucinations and altered perceptions.

現在，它必須理解增加的資訊，並開始用幻覺和改變的感知來填補空白。

In order to cope, living plants might start to grow faces.

為了應對，活的植物可能會開始長臉。

The brain will never stop trying to make sense of the world, but now it is using new parts of the brain.

大腦永遠不會停止試圖理解這個世界，但現在它正在使用大腦的新部分。

In fact, people who are color blind report being able to see certain colors for the first time.

事實上，色盲的人都表示能夠第一次看到某些顏色。

While on psychedelics, a child's brain is actually similar to an adult brain on psychedelics.

在服用迷幻藥的時候，孩子的大腦其實和成人服用迷幻藥的大腦是相似的。

As an adult, you have learned through experiences and prune your neurons to deal efficiently based on past experiences for kids.

作為一個成年人，你已經通過經驗學習，並根據過去的經驗為孩子們修剪神經元，以有效地處理。

Most experiences are new when they encounter a situation, their brain is not efficient looking more like this graph on the right than this graph on the left.

大部分經驗都是新的，當他們遇到一個情況時，他們的大腦效率不高，看起來更像右邊這張圖，而不是左邊這張圖。

This explains their curiosity, slower processing obsession with nature and why they're better than adults.

這就解釋了他們的好奇心、處理速度較慢對自然的痴迷，也解釋了為什麼他們比成年人更優秀。

At some intelligence tasks involving creativity or just straight up, white kids act like they're on drugs.

在一些涉及到創造力或者是直接的智力任務中，白人孩子就像吸毒一樣。

Existentially distress and a fear of dying usually means an overactive default mode network.

存在困擾和對死亡的恐懼通常意味著過度活躍的默認模式網絡。

Obsessive self reflection.

執著的自我檢討。

Ah, fear of losing consciousness or the ego.

啊，害怕失去意識或自我。

This is why, in recent years, psychedelic therapy has become a popular treatment for terminal illness and coping with end of life.

這也是為什麼近年來，迷幻療法成為治療絕症和應對生命末期的熱門療法。

Fear addiction could be related to the story you have built about yourself, leading to some promising studies using psychedelic therapy to decrease addiction to smoking or alcohol.

恐懼成癮可能與你建立的關於自己的故事有關，導致一些有希望的研究使用迷幻療法來減少對吸菸或酒精的成癮。

Indigenous Americans have long used the psychedelic peo T to treat the alcoholism introduced by colonizers and played communities since the genocide.

土著美國人長期以來一直使用迷幻藥peo T來治療殖民者引入的酒精中毒，併發揮了種族滅絕以來的社區。

From what Europeans studies that use hallucinogens as therapeutic tools have professionals who lead the trip and place importance on the set and setting.

從歐洲人的研究，使用致幻劑作為治療工具，有專業人士誰上司的行程，並將重要性設置和設置。

The stakes are high when letting this much information into the brain and can lead to a bad trip.

當讓這些資訊大量進入大腦時，風險很大，可能會導致糟糕的旅行。

But one thing is for certain.

但有一點是肯定的。

Hallucinogens are helping us understand how the brain works.

致幻劑正在幫助我們瞭解大腦的工作原理。
