In these experiments, however, volunteer healers with no previous experience or belief in healing with intent were successful in producing full lifespan cures in mouse cancer models that are normally fatal. Further, fMRI brain data indicate a non-conscious response in the brain of the healer to the need for healing. Successful healing has been produced by volunteers who have experienced a wide range of subjective sense of connection (and lack of connection) to their experimental mice, and fMRI data indicate a strong and reliable difference in healer brain output in which the healer and experimenter were blinded as to the health needs of experimental animal subjects.
