LSD is one of the most powerful drugs ever created, and for the first time ever, scientists at Imperial College London have successfully image scanned human brains that are under the influence of the psychedelic drug.
The study has had profound impacts on our understanding of consciousness. As one researcher explained, “Normally our brain consists of independent networks that perform separate specialised functions, such as vision, movement and hearing - as well as more complex things like attention. However, under LSD the separateness of these networks breaks down and instead you see a more integrated or unified brain. In many ways, the brain in the LSD state resembles the state our brains were in when we were infants: free and unconstrained.”
Designer Meaghan Li has created these colourful – and very informative – posters which show how our brain reacts on drugs.
‘Each poster is either figurative (the dissociative circles for ketamine and the sharp spikes for cocaine), visual (the psychedelic patterns for acid and DMT), or literal (the ghost-like spirit for Heroin). The one that stumped people the most was the marijuana one.
‘I tried to show melting, taking the edge off, and the subtle visual effects that it can cause.’
