You are the church and the tree and the hill.Īlbert Hofmann, the discoverer of LSD, described this in his book LSD: My Problem Child. You are the pizza and the world beyond the windowsill. This can create the perception that you and, say, the pizza you're eating are no longer separate entities. Your brain on acid, flooded with signals crisscrossing between these regions, begins muddling the things you see, feel, taste or hear around you with you. Tagliazucchi speculates that what's happening is a confusion of information. "The stronger that communication, the stronger the experience of the dissolution ," says Enzo Tagliazucchi, the lead author and a researcher at the Netherlands Institute for Neuroscience. Their sensory cortices, which process sensations like sight and touch, became far more connected than usual to the frontal parietal network, which is involved with our sense of self. For those on LSD, activity in certain areas of their brain, particularly areas rich in neurons associated with serotonin, ramped up. Scientists gave 15 volunteers either a drop of acid or a placebo and slid them into an MRI scanner to monitor brain activity.Īfter about an hour, when the high begins peaking, the brains of people on acid looked markedly different than those on the placebo. The sensation that the boundaries between yourself and the world around you are erasing correlates to changes in brain connectivity while on LSD, according to a study published Wednesday in Current Biology. The hallucinogenic drug might be causing this by blurring boundaries in the brain, too. Some users of LSD say one of the most profound parts of the experience is a deep oneness with the universe. That out-of-body experience is happening in your brain.
