Explain Sensory deprivation.

Sensory deprivation is the intentional reduction or elimination of stimuli to one or more of the senses. Typically achieved through isolation tanks or controlled environments, it aims to induce a state of sensory isolation. This restricted sensory input may lead to altered perception, hallucinations, and changes in consciousness. Studied for its psychological effects, sensory deprivation provides insights into the role of sensory stimuli in maintaining mental well-being and the brain's ability to generate perceptions in the absence of external input.
