Apr 13, 2016 5:09 PM UTC What exactly happens to the brain on psychedelic drugs? A small new [study](http://www.cell.com/current-biology/fulltext/S0960-9822%2816%2930062-8), published in the journal _Current Biology_, peeked inside the brains of 15 people during an acid trip and found brain-scan backup for a popular drug cliche: that the tripper feels at one with the universe. Fifteen healthy people, who were experienced users of lysergic acid diethylamide, or LSD, came twice to a lab in London. (LSD is illegal in the UK, but it’s possible to use it in research with special permissions.) Once, they were injected with a small amount of LSD (75 micrograms); the other time they received a saline placebo. After an hour, to let the effects settle in, they got into an fMRI brain scanner, which captured images of what went on in their brains. The researchers asked the people to rate their mood changes—getting answers like “I’m tripping like crazy” or “nothing is happening”—their visual distortions and their intensity of ego dissolution: a loss of self-identity and sense of connection to the environment outside of oneself that reportedly happens to people when they take LSD, [which is illegal in the United States](http://www.dea.gov/druginfo/drug%5Fdata%5Fsheets/LSD.pdf). “You don’t recognize yourself as a separate being from the universe,” says study co-author Enzo Tagliazucchi, a neuroscientist at the Royal Netherlands Academy of Arts and Sciences in Amsterdam. “It feels, in a way, like transferring the consciousness from within your body to the outside world; the focus is in the objects that surround you rather than inside.” Tagliazucchi and the team wondered if they could find some changes in the brain related to this feeling of ego dissolution. When they looked at the regions of the brain involved in introspection, or thinking about oneself, and sensory areas that perceive the outside world, they found that these networks were communicating more intensely than usual. “When we measured the brains of subjects who were really blown away by LSD, who had a really strong feeling of ego dissolution, they were also the ones who had the strongest increase in communication between the network of regions in charge of introspection and the network of regions in charge of perceiving the external world,” Tagliazucchi says. In another neuroimaging [study](http://www.pnas.org/content/early/2016/04/05/1518377113.full?sid=4396f1ed-3885-49bd-bab1-21b161793e12) published earlier this week in the journal _PNAS—_conducted by many of the same authors, including Tagliazucchi—the researchers found that LSD changes visual information in the brain. While people are on acid, they start to see activity going on in the brain, which is normally suppressed from perception, Tagliazucchi explains. The ability to see this internal activity is likely responsible for hallucinations and visual distortions on LSD, he says. Tagliazucchi acknowledges that more research is needed—not just to provide biological evidence for the reported experiences of people on acid, but to explore a potential therapeutic approach for people with anxiety or depression. Instead of taking a pill every day to change brain chemistry, he says, it’s possible that psychedelics could provide a few hours to break out of constricted thought patterns. “If you combine this with psychotherapy during that window, you have this chance to reflect on things that your depression normally wouldn’t allow you to focus on,” he says. We’re a long way from acid-assisted therapy going mainstream; LSD research like the kind in London is only legal in a handful of places around the world, and the science is still in very early stages. “Now is the first time we have both fMRI machines and clearance to do experiments with LSD,” Tagliazucchi says. ## Transcript [ MUSIC ] [ UNKNOWN ] Acid just in love with life, and you're dreaming all the time. Love, sex, dream. [ MUSIC ] When you hit acid it just sounds dangerous, so off rift everybody's just like nah I'm against it. I don't **** with that ****. You'll see **** like weird creatures that you never saw, but you're not actually scared of them. [ MUSIC ] The first time experience of LSD for me, it was crazy. I mean, what do you guys expect to hear from my besides that. I don't know if I can verbally tell you how LSD looks. I can't explain that, I can only articulate it through my art. [ MUSIC ] I enjoy doing visuals. Enter the Void. That's what it was inspired by. Is this going to make you a junkie? I know I'm not a junkie. Are you going to be like family from now on? I watched that film. We wanted to do something that was inspired, that paid homage to it. All the imagery was just similar like Tokyo and some bright colors. [ MUSIC ] We started the beat from scratch I was just talking to Jim Johnson. He pulled out the guitar. [ MUSIC ] Before you knew it, we had a masterpiece. I was in that audition feeling like Prince. [ LAUGH ] [ MUSIC ] What can I do if somebody hates that I'm taking LSD. What can I do. LSD is not a popular drug like as much as marijuana per say, or tobacco cigarettes, or liquor. People can't really relate to it that much. I didn't expect a white audience to go crazy. No, it was natural. I wasn't doing it. I felt like [ UNKNOWN ] inspired me mostly around that time. It changed my life, and I really wanna give people drugs through music. [ LAUGH ] People try that all the time. We're trying. You know. [ MUSIC ] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4292298/lsd-acid-trip-drugs-brain/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4292298/lsd-acid-trip-drugs-brain/"},"headline":"Here’s What LSD Does To the Brain","datePublished":"2016-04-13T17:09:50.000Z","dateModified":"2026-08-04T07:55:53.457Z","description":"There's a reason it makes people feel more connected to the universe","url":"https://time.com/4292298/lsd-acid-trip-drugs-brain/","keywords":["Research","Drugs","LSD","Neuroscience","apester"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt4eb9e8e4e1c0d452/6988604c8e06017e23461fdb/brain-health-illo.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Mandy Oaklander","jobTitle":"Oaklander is a senior editor at TIME.","url":"https://time.com/author/mandy-oaklander/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt4eb9e8e4e1c0d452/6988604c8e06017e23461fdb/brain-health-illo.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"TIME.com stock health brain","caption":"TIME.com stock health brain","creditText":"Illustration by Sydney Rae Hass for TIME","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/research/","name":"Research"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4292298/lsd-acid-trip-drugs-brain/","name":"Here’s What LSD Does To the Brain"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"A$AP Rocky Explains How LSD Influenced His Visuals","description":"\"I really want to give people drugs through music.\"","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/BXVqwktS/poster.jpg?width=720","uploadDate":"2015-11-05T14:21:03.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/BXVqwktS.m3u8","embedUrl":"https://time.com/4292298/lsd-acid-trip-drugs-brain/","duration":"PT2M42S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/4292298/lsd-acid-trip-drugs-brain/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
