23. Human neural energy transfer - B.

This diagram generalises our human neural energy system yet further, by schematising BOTH SIDES of the brain working together. Our right and left brains together engage in both visceral mental activity which is largely unconscious and somato-branchial activity which is largely conscious.

The concept of essential symmetry in neural activity began to be modified in the early 19th century and since then clear evidence of major differences of emphasis between the activities of our left and right brain hemispheres has been recognised.

Very simplistically, left cortical activity has been shown to be dominant in analysis and language and right cortical activity in synthesis and emotion. This laterality has been shown to occur in a large selection of other animals and so now is seen as an evolved pattern.

Again, the pattern has been frequently clinically confirmed, as illustrated in the next two diagrams.
