Immersion in the OVO Whole-Body Perceptual Deprivation chamber, a homogeneous sensory environment, consistently produces positively connotated, bodily-oriented, and cognitively dedifferentiated subjective states in most people. Semi-structured interviews with 32 participants, analyzed by three independent evaluators, showed significant consensus on experiences such as softened boundaries across time and sensory modalities. These subjective findings align with prior electrophysiological results that reported increased delta and beta activity in the left inferior frontal cortex and left insula during immersion.
