The Brain, Sensory Deprivation and Isolation

1307

The documentary film “The Brain, Sensory Deprivation and Isolation” delves into the effects of reduced stimulation on the human brain. Sensory deprivation, or the deliberate reduction or removal of stimuli from one or more of the senses, is explored in the film. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and ‘gravity’.

The film examines the various uses of sensory deprivation, from alternative medicine to psychological experiments and in interrogations by some armed forces within NATO. It also looks at the phenomenon of perceptual deprivation, also known as the ganzfeld effect, where a constant uniform stimulus is used instead of attempting to remove stimuli, which leads to effects similar to sensory deprivation.

The film explores the short-term and long-term effects of sensory deprivation, highlighting the benefits and drawbacks of reduced stimulation. It also delves into the ethical implications of using sensory deprivation as a means of interrogation, and the impact it can have on the human brain.

“The Brain, Sensory Deprivation and Isolation” is a must-watch for anyone interested in the effects of reduced stimulation on the human mind.
