the knee jerk of the standard neurological examination. Such phenomena were already well known in the late 1930’s in what W.R. Hess and later John Flynn, following electrical stimulation of cats in the lateral hypothalamus, called “hypothalamic rage.” In the late 1940’s and 1950’s, work by National Institutes of Mental Health’s Paul MacLean attributed it to the actions of parts of the emotional “limbic” brain, particularly the fear-rage-attack coloring of experience by the temporal lobe’s amygdaloid nucleus. Modern imaging studies in man have shown that this source of emotional coloring is activated by new information, even before the more rational parts of the neocortical brain processes it. How we feel about something new arises before what we think about it. These survival-oriented states of fight or flight are known to be biologically universal and demonstrable in even single cell organisms. A greater contribution to my brain metaphysics followed observations that after several seconds of stimulation of other brain stem sites, the cats became alert but quiet, staring into space for several minutes. Then, they circled slowly and curled up on the ground. This was followed by several minutes of grooming and loud purring. Difficult to handle cats became transiently tame, some coming close for petting. | found that these same sites also increased the amplitude and reduced the threshold for the cat’s knee jerk reflex. Responsiveness increased with calmness. Particularly interesting was the finding that electrical induction of this purring state could immediately stop on-going stimulation-induced episodes of hissing rage. | referred to these experiments with my friends as my neurophysiological studies of Old Testament vengeance and New Testament forgiveness. It seemed that the hissing rage would produce eye for an eye and a tooth for a tooth hypertension, the talon principle of the Old Testament and Koran. New Testament forgiveness would yield low blood pressure healt
