In 1954, neuroscientist John C. Lilly developed the worldâs first sensory deprivation tank so that he could access deeper recesses of the mind. By filling a soundproof and lightproof chamber with warm water saline enough to replicate the sensation of zero gravity, Lilly found a way to curtail external distractions and harness internal strength. âThe freedom from external reality was taken as a very positive point,â he wrote of his first LSD trip in the tank. âOne could go anywhere that one could imagine one could go⦠I traveled through my brain, watching the neurons and their activities.â
