into action without restraint.8 Hemorrhages in the thalamic region often result in marked lability of affects. Diffuse nutritional disturbances of the cortex usually give similar symptoms, as in organic brain diseases , .10
It should be remembered that in the human nervous system the co-ordinated working of the higher and lower centres is a necessity for the optimum working of the whole. In cats and dogs deprived of the association areas of the cortex, the difference is not so marked. They still behave in a co-ordinated way, provided the thalamic regions are intact. Even in a child without a cortex, we find facial grimaces if we give him something bitter, but higher adjustments are impossible.11 The general 'inhibitory' and regulative action of the higher centres increases with the differentiation of the nervous system; and in man this becomes of paramount importance. This has been shown empirically. For instance, in man and dogs strong negative action on the flow of gastric juices may be 'psychic' in origin. This negative action is weak in the guinea pig, although it is discovered on decerebration. With the tortoise, also, there is some acceleration of the movements of the stomach after decerebration, but in a frog we do not find any negative influence at all."
The facts given above were established through anatomical and physiological structural examinations. If the functioning of the nervous system is examined from the point of view of colloidal chemistry, the gross non-surgical lesions become interpretable as the result of changes in colloidal behaviour. Thus Doctors Wilder D. Bancroft, J. Holmes Rich-ter, H. Beckett Lang, John A. Paterson, Walter Freeman, and others demonstrated that it is possible to find a correlation between the functional psychoses and the state of dispersion of the nerve colloids. For instance, in dementia praecox the nervous system appears in a state of colloidal over-dispersion; and in manic depressive psychoses, in a state of decreased dispersion.13 It is interesting to note that in infants the colloids appear more dispersed than in grown-ups and probably similar conditions will be found in cases of infantilism. The above-mentioned scientists have found, also, that the colloidal behaviour of the nervous system can be altered by special chemical treatment with drugs, carbon dioxide, oxygen., with specific reactions on the psycho-logical level. As s.r involve electrical occurrences fundamental in colloidal behaviour, similar symptoms on psycho-logical levels may imply corresponding sub-microscopic colloidal states. Taking into consideration the structural characteristics of colloidal behaviour and the elaboration of technical means, we may discover that semantic re-education must involve differences in electrical potentials., and result in differences in colloidal be-
