If excessive action of the brain or spinal cord be analogous in its effects to galvanism of a spinal nerve, it might be supposed to cause vaso-motor paralysis and hæmorrhage. 3d. In general exhaustion of the nervous system, both of its ganglionic and cerebro-spinal apparatus, the vaso-motor nerves suffer with the rest, and the blood-vessels lose their tone in consequence.
We have learned that the human body is a confederation of various groups of living cells; that in the earliest stages of man's evolution, these cells were all of the same general type; that as such they were free-living, free-thinking and intelligent organisms as certainly as were those unicellular organisms which had not become members of any group or association; that through the processes of evolution, heredity and adaptation, there has come about in the course of the ages, a subdivision of labor among the cells of our bodies and a consequent differentiation in kind whereby each has become peculiarly fitted for the performance of its allotted functions; that, nevertheless, these cells of the human body are still free-living, intelligent organisms, of which each is endowed with the inherited, instinctive knowledge of all that is essential to the preservation of its own life and the perpetuation of its species within the living body; that, as a part of the specializing economy of the body, there have been evolved brain and nerve cells performing a twofold service first, constituting the organ of a central governing intelligence with the important business of receiving, classifying, and recording all impressions or messages received through the senses from the outer world, and, second, communicating to the other cells of the body such part of the information so derived as may be appropriate to the functions of each; that finally, as such complex and confederated individuals, each of us possesses a direct, self-conscious knowledge of only a small part of his entire mental equipment; that we have not only a consciousness receiving sense impressions and issuing motor impulses through the cerebro-spinal nervous system, but that we have also a subconsciousness manifesting itself, so far as bodily functions are concerned, in the activity of the vital organs through the sympathetic nerve system; that this subconsciousness is dependent on consciousness for all knowledge of the external world; that, in accordance with the principles of evolution, man as a whole and as a collection of cell organisms, both consciously and unconsciously, is seeking to adapt himself to his external world, his environment; that the human body, both as a whole and as an aggregate of cellular intelligences, is therefore subject in every part and in every function to the influence of the special senses and of the mind of consciousness.
Every bodily movement or function that you can start or stop at will, even to such seemingly unconscious acts as winking, walking, etc., is controlled through the cerebro-spinal system.
With hydrotherapy and the other natural methods they have treated successfully typhoid fever. diphtheria, smallpox, appendicitis, cerebro-spinal meningitis and all other acute diseases.
Captain Ellis began an investigation into the grouping of the various strains of "meningococci" the organism causing cerebro-spinal meningitis, with the ultimate object of obtaining a more efficient anti-serum for the treatment of this disease.
The Cerebro-Spinal System consists of all that part of the Nervous System contained within the cranial cavity and the spinal canal, viz., the brain and the spinal cord, together with the nerves which branch off from the same. This system presides over the functions of animal life known as volition, sensation, etc.
Inflammation of the meninges or brain may follow injuries, not only to the brain itself, but to the scalp and adjacent parts, as the orbit and ear. Inflammation does not usually come on at once, but after variable periods. That the wound has penetrated the meninges is shown by the escape of cerebro-spinal fluid.
It is true that at a later stage of evolution psychic sensitiveness reappears, but it is then developed in connection with the cerebro-spinal centres, and is brought under the control of the will. But the hysterical and ill-regulated psychism of which we see so many lamentable examples is due to the small development of the brain and the dominance of the sympathetic system."
The period of their development, the influence of such development on the entire nutrition of the body, the irregularities of nutritive or of cerebro-spinal action, that may be caused by irregularities in such development, are also completely analogous.
Luys holds that the brain, as a whole, changes its position in the cranial cavity according to different attitudes of the body, the free spaces on the upper side being occupied by cerebro-spinal fluid, which, obeying the laws of gravity, is displaced by the heavier brain substance in different positions of the body.
