Researchers at Imperial College London believe that they know what effect LSD has on the human brain. After pumping test subjects full of the stuff and shoving them in an MRI, the team learned that the drug makes our brains behave similarly to that of a baby. In order to understand this, imagine that your mind is the single floor of an office, with cubicles running as far as the eye can see. Each cubicle is responsible for different jobs, such as memory, balance and hearing, only talking to each other on the annual company retreat. LSD is like a disgruntled former employee, temporarily smashing down the plyboard dividers and forcing everyone to collaborate.
