It is noted in Chapter Five that Wilder Penfield studied the human mind and acknowledged a spiritual element in Man when he accepted the dualist hypothesis. . . . He ultimately proposed a form of energy within the mind that enables its action on the brain. . . . He . . . asked if there is a force available to the mind which does not depend on such electrochemical circuits but is interactive with it. He posited that the mind has energy, the form of which is different from that of electrochemical action potentials that traverse the axonal and dendritic pathways of neural networks.
