Healers claim that they can relieve, and often heal, injury and illness against the odds of medical prognosis. Skeptics say that such claims can be accounted for by possible misdiagnosis, uncritical reportage, placebo response, and coincident natural improvement. Their a priori objection is that subjective intention in one person cannot, of itself, affect the physiology and/or mental processes of another person. This a priori objection becomes invalid if experimental evidence, using simultaneous electroencephalographic recordings from two or more brains, has demonstrated that direct brain-to-brain communication can occur. Evidence that something very unusual is occurring during the healing transaction comes from recordings of anomalous electrical and magnetic fields generated by healers when they are in the intention-to-heal mindset.
