Sensory Deprivation Tanks – isolation tanksPosted: February 8, 2014
The Sensory Deprivation Tank was introduced by John C. Lilly in 1954. Lilly’s intentions were to answer the question as to what keeps the brain going and the origin of it’s sources: if the hypothesis that energy sources are biological and internal and not external, then the brain would theoretically sleep during the time in the tank. The tank deprives the senses by eliminating sound, sight, and eventually touch as participents float in skin-temperature salt water (therefore the water eventually ‘disappears’). This means all that is left is the mind, allowing subjects to heighten their sense of awareness. These tanks are now used as stress therapy, alternative medicine and meditation, meaning that the mind continues to work without external stimulus for the senses.
