![xtx fibres to the heart, vessels, and viscera, or rather probably to regions of the sympathetic system, from which these parts are supplied. The inference we have now arrived at is that the units of the cerebral hemisphere (in the region of the corpus striatum, at least) represent potentially the whole processes of the body. If this be so we can understand how it happens that in cases of epilepsy [beginning by loss of consciousness, i.e.y the discharge beginning in the highest nervous processes], besides obvious convulsion, we have premonitory shivering, pallor of face, and increased flow of saliva, and in some cases vomiting. Thus, too, we see how it is that emotional mani- festations accompany intellectual phenomena. Emotional manifestations are wide and yet temporary bodily states, and we have seen that the heart, arteries, and viscera, as well as the large muscles of the body, are represented in the units of the cerebrum.” The statement that muscle, viscera, &c., are represented in the organ of mind,” and in the very highest parts of that organ, at first glance, appears extravagant. It is to be noted that it is in general agreement with independent statements of Laycock, Bain, and Lewes. Laycock says (Mind and Brain,” Vol. ii, p. 144)—The functions of the hemispherical ganglia, as the organs of thought and mental action proper, are in unity with all the processes of life what- ever, whether they be termed vegetative or animal” (no italics in original). Bain writes that the organ of mind is not the brain by itself; it is the brain, nerves, muscles, organs of sense and viscera.” It accords with Lewes’s statement that every mental phenomenon has its corresponding neural phenomenon .... every neural phenomenon involves the whole organism.” The highest nervous processes are poten- tially the whole organism. Moreover, the seemingly extrava- gant statement accords closely with what disease shews. I wish to say that I have not arrived at the above conclusion](https://iiif.wellcomecollection.org/image/b22355078_0025.jp2/full/800%2C/0/default.jpg)
