Sensory DEPRIVATION and ISOLATION:

Imagine being alone, in a dark room with all of your senses deprived. Awful right? Well, believe it or not, this is a punishment that is used by various people for various reasons. This punishement is known as sensory deprivation (a very controversial topic among some people). Some of the people who use these are: military armies, Navy, and in general all of those people who want to punish a delinquent, terrorist, traitor, etc. The people who use this method, usually use it as an aid of interogation. 
Now... what does sensory deprivation and isolation do exactly? Quite simply, sensory deprivation goes deep into the human minds and/or brain by removing stimuli to one´s senses. This consequently causes emotional trauma, because in order for the brain to stay healthy and working adequately, it needs stimulation. It also has to do with coordination. 
To conclude, sensory deprivation and isolation is a method that removes stimuli to one´s sense and goes deep into the mind affecting them emotionally. This is used as an aid of interogation to those people who want to punish delincuents, terrorists and traitors.
