Psychedelic or "magic"mushrooms have been ingested by humans for over 9000 years.Even today,this naturally grown fungus is commonly used as a recreational drug.causing hallucinations,but how exactly does it work?The main psychoactive ingredient in shrooms is call psilocybin.When ingested,the body breaks it down into the active drug psilocin,which makes its way to the brain.

人类食用迷幻菇/魔菇,已有9千多年历史,即使是如今,这种天然生长的菌类依然常被当做娱乐性药物,用于致幻,但其致幻的原理是什么?魔菇里起致幻作用的主要成分是裸盖菇素,食用之后,身体会将其分解成活性致幻剂二甲-4-羟色胺,进而进入大脑.

And here,it begins to prevent the reuptake of the neurotransmitter serotonin,increasing its activity.On top of this,psilocin actually has a similar chemical structure to serotonin,meaning it can also bind to and stimulate receptors in the brain.This amplified stimulation causes you to perceive and experience things without any real stimulus-also know as hallucination.

此时它开始防止神经递质血清素的再摄取,以此来增加自身活性,另外,二甲-4-羟色胺与血清素有着相似的化学结构,也就是说它可以结合并且刺激相应的大脑接收器,这种放大的刺激使你感知和体验到,并不存在的事实---即幻觉.

These can be of a varying nature,from visual to auditory sensations,or mystical and insightful feelings.And while the experience can be quite enjoyable,some users have reported very unpleasant episodes.These feelings generally last between 3-8 hours,but could feel much longer as the drug alters your sense of time.

这些幻觉多种多样,从视觉到听觉,甚至可能是神秘和深刻的感觉,有些人会体验到一些愉快的幻觉,也有人经历了不愉快的幻觉,致幻觉效果会持续3到8个小时,但也会因为药物对时间感的影响,而觉得效果漫长.

Scientists have also suggested that the brain may temporarily rearrange itself by inhibiting normal brain activity and immediately creating new biologically stable brain connections.This,ultimately,makes it harder to determine reality from fantasy,and amplifies your intensity of thought which makes planning ahead and self conscious thinking almost impossible.

科学家认为,大脑可能会通过制约正常脑活动进行自我调整,并且立刻建立起新的稳定的脑关系,而这种变化,令服用者更加难以分辨真实和虚幻,并且放大思考强度,使其无法完成预先计划和自我意识思考.

We also see activation in the hippocampus and anterior cingulate cortex which are associated with dreaming.Finally,specific emotional regions of the brain are chemically activated,which can lead to a sense of expanding consiousness.And because the drug temporarily alters the paths in your brain,"thinking outside of the box"becomes extremely natural.

我们知道,海马体与前扣带皮层的激活,与梦境有关,另外 大脑特殊的情感区域被化学激活,会造成意识放大,由于药物临时改变了大脑回路,"不守框条的思考"变得极其自然.

In a famous US study,36 college educated participants were given psilocybin and observed in a laboratory.1/3rd of the participants reported the experience as the single most spiritually significant moment in their lives,with 2/3rds putting it in their top five.Two months after taking the drug,79% of the participants reported increased well-being and satisfaction.

美国一个著名的研究中 36名大学生志愿者,服用裸盖菇素 并在实验室中接受观察,三分之一参与者表示,这是他们人生最重要的精神体验,三分之二的人则认为这属于人生前五的主要时刻,服用两个月后,79%的参与者表示幸福感和满意提升了.

Friends and family were also interviewed and agreed with these claims But it's not all so positive-22% of the clinically tested individuals experienced fear and paranoia at certain points during their trip.And because of the state of their brains,these typically manifested as terrifying and uncontrollable hallucinations.

他们的亲朋在接受采访时亦同意此说法,但也并非都是好的体验,22%的体验者在实验过程中,某些时刻感觉到了恐惧和偏执,由于他们的大脑状态,这些症状主要表现为恐惧和不受控的幻觉.

Though much is still unknown about shrooms,they're not considered clinically addictive and cause little toxicity to other organ systems.

虽然关于魔菇尚有许多未解之谜,但它们似乎并不会造成上瘾问题,对其他器官系统存在少许毒性.

In fact,a UK study found that they cause the least amount of damage-both to the individual and others-when compared to other recreational drugs.Ultimately,scientists believe the laws need to change around clinical testing of the drug so advanced research can be executed to fully understand both the positive and negative effects that this "magic"fungus has on our brains.

事实上 英国一项研究发现,无论对个体还是他人而言,与其他娱乐性药物相比,魔菇的危害性最小,科学家们觉得关于药物临床试验的法律规定,应该稍作修改,这样关于魔菇对大脑影响的先进实验才能继续进行,进而找出它对大脑的积极和消极影响.
