Dr Joe Dispenza explores the science behind spontaneous remissions and how people heal themselves of chronic conditions and even terminal diseases. He and his team do brain mapping with electroencephalograms (EEGs) and individual energy field testing with a gas discharge visualization (GDV) machine, as well as measure both heart coherence with HeartMath monitors and the energy present in the workshop environment before, during, and after events with a GDVSputnik sensor.
