Notes of Dads 6. Neurophysical Hypothesis – Humankind.

9) The Neurophysiological Hypothesis
This is derived from the Papez-MacLean theory of emotions. Dr Paul Maclean was the head of the laboratory of Brain Evolution and Behaviour, Maryland, USA. It is a good start if you are on a road to your own personal discovery of who and what you are. It is quite simple.
This theory is based on the differences in anatomy and function between the archaic structures of the brain shared by men with the reptiles and lower mammals, and the ‘specifically’ human neocortex, which evolution superimposed on them.
10) The result of this evolutionary blunder is an uneasy coexistence, frequently erupting in acute conflict, between the deep ancestral structures of the brain, mainly concerned with instinctive and emotional behaviour, and the neocortex, which endowed man with language, logic, and symbolic thought.
11) MacLean writes, "Man finds himself in the predicament that nature has endowed him essentially with three brains, which despite great differences in structure, must function together and communicate with one another.
a) The oldest of these brains is basically reptilian.
b) The second, has been inherited from the lower mammals, and the
c) third, is a late mammalian development, which has made man, peculiarly man, "While the antediluvian structures of the very core of our brain, which control instincts, passions and biological drives, have hardly been touched by evolution, the neocortex of the hominids expanded in the last half-a-million years at an explosive speed which is without precedent in the history of evolution, so much so that some anatomists compared it to a tumorous growth. But explosions do not produce harmonious results".
12) The result in our case seems to have been that the rapidly developed thinking cap, which endowed man with his reasoning powers, did not become properly integrated and co-ordinated with the ancient emotion bound structures on which it was superimposed with such unprecedented speed. The neural pathways connecting the neocortex with the archaic structures of the mid-brain are apparently inadequate.
13) Thus the brain explosion gave rise to a mentally unbalanced species, in which the old brain and the new brain, emotion and intellect, faith and reason, were at loggerheads. On the one side, the pale cast of rational thought of logic, suspended on a thin thread all to easily broken, on the other, the native fury of passionately held irrational beliefs, reflected in the holocausts of past and present history.
14) If neurophysiological evidence had not taught us to the contrary, we would of have expected it to reveal an evolutionary process that gradually transformed the primitive old brain into a more sophisticated instrument, as it transformed gill into lung, or the forelimb of the reptilian ancestor into the bird’s wing, the flipper of the whale, and the hand of man.
15) But instead of transforming old brain into new, evolution super-imposed a new superior structure on an old one, with partly overlapping functions and without providing the new brain with the clear-cut power of control over the old. MacLean has coined the term "schizophysiology" for this shortcoming in the nervous system.
16) The  hypothesis that this type of "schizophysiology" is part of our genetic inheritance, built into the species, as it were, could go a long way towards explaining some of the pathological symptoms already listed. The chronic conflict between rational thought and irrational beliefs, the resulting paranoid streak in our history, the growth curves of science and ethics, would at last become comprehensible and could be expressed in physiological terms.
And any condition that can be expressed in physiological terms should ultimately be accessible to remedies!

My First family, second marriage, bringing up my 18-year-old twins, boy, and girl. I am a third generation Humanist, who has some old handwritten information and notes; collected over many years. Someone may find the articles interesting, or helpful. They could bring back a little ‘reality’, after being ‘shocked’ and ‘brainwashed’, by some malicious group, or institution (REBT Therapy). People should know better, than to do this, to our very young, and the ‘obviously’ vulnerable! Go to easily accessible, non-superstitious knowledge that is not charlatanism! The blog has given me an incentive to order my thoughts, learn, and read up again, after a few non-thinking years of (very silly) imagination and passion. Why not, get your own key to a ‘door’, customise it to suit you, and it can be, all of your very own! Don’t believe, or be led by someone else’s; inherited, stupid, and a very likely (past, and not of today’s) ‘totally preposterous reality’s’. Only some interest in the ‘really big questions’, keeps life above the level of a farce, and very little else! KEEP THINKING! Some of the posts may need some correcting. Interests: REBT Counselling, Atheism, Secularism, Humanism, Psychology, Reading, Popular Science, School Ethos, Philosophy, History, Family, Parenting, Psychology, Horse Riding, Sailing, Rescue Boat Driver, Skiing (Teppichswinger), TV Documentaries, Motorbike Cross Country Riding, Volunteer Sports Stewarding, Writing, Primitive Man, Pre-history, Social Anthropology, British Humanist Association, BHA, Meaning of Life, The Big Questions, Where am I, What am I, Why am I, Hippie Love, Knowledge, Education, Globalisation. Favorite quote: “The world belongs to those who, at least to some degree, have figured it out.” Carl Sagan, ‘The Demon Haunted World’, ‘Contact’, and other famous books DVD ‘Cosmos’. The warning of another and horrendous, “Age of Superstition”. “Isn’t there something deeply absurd in the presumption that children ought to inherit beliefs from their parents. It can be deeply damaging, even lethally divisive. A ‘them’, with an ‘against us’, mentality” – Professor Richard Dawkins. “The will to believe is stronger than mere reason in the vast majority of people” – Dr J.Brown, Army Psychologist of the 1960′s. Humans will believe in almost anything, in fact, they seek it! Why? “98% of us, trained to be just good consumers, let’s train our children to be the 2% who have their very own creativity and discernment”; quote by a famous surreal artist. “The lack of reason brings forth monsters”. “Global interconnectedness is lethal against mass religion, nationalism, racism, and other destructive memeplexes. Let us connect everybody they hate it in restrictive regimes”; from the ‘meme learning group’, Richard Brodie’s book, ‘Virus Of The Mind’ (Richard Brodie a designer for ‘Microsoft Word’). Following on, J.Bronowski, and ‘The Ascent Of Man’ TV series, and a book with the last DVD in this series, ‘The Long Childhood’ being especially revealing. ‘Prehistory’ and the ‘Making of the Human Mind’ by Colin Renfrew, with P.Wilson’s, ‘The Domestication of the Human Species’, and Nigel Spivey’s, TV series and book, ‘How Art Made The World’, offers some further explanations.
