Summary
AI-generated from the abstractA pilot test with one participant found that 30 serial sessions of guided meditations in a sensory isolation tank changed brain structure, triggered the relaxation response, and generated greater physical, psychological, and mental well-being. Cerebral volumetric changes were measured by brain magnetic resonance imaging, and physiological variables were documented through neurobiofeedback equipment before and after the sessions.

Abstract
This study aimed to investigate the cerebral volumetric changes measurable by brain magnetic resonance imaging, as well as the different physiological variables documented through neurobiofeedback equipment, before and after 30 serial sessions of guided meditations in a sensory isolation tank. A pilot test was carried out, with a single subject, and it was concluded that serial sessions of meditations in flotation tanks changed the brain structure, triggered the relaxation response, generating greater physical, psychological and mental well-being for the research participant.
