Gutieras, the government expert, has a pint of yellow fever baccilli in his cerebrum. He carries the plague with him, just as a man suffering with mania a potu carries his cargo of monkeys. Had he been called to see Simon's wife's mother, he would have declared that she had a case of Yellow Jack and spread a panic through all Judea.
We understand from knowing the philosophy of miracles the reason why we do not always succeed. We can not always secure the impressible condition by producing the quiescence of the large brain. But if we understand the theory of hypnotism we shall be able to put the cerebrum at rest and secure the passive impressible state of the cerebellum; that is, an introverted condition of the mind.
Heaton reports a case in which, by an explosion, a tamping-iron was driven through the chin of a man into the cerebrum. Although there was loss of brain-substance, the man recovered with his mental faculties unimpaired. A second case was that of a man who, during an explosion, was wounded in the skull.
Her cerebrum does not co-act with her cerebellum. In other words, her conscious mind, for lack of means to express itself, is for the time being dormant as in sleep. "But it is not like ordinary sleep. Such is induced by fatigue of the nerve channels. This young woman's condition is produced by shock; and since there was no physical violence, we must conclude that the shock was psychic.
This has not yielded any marked increase in the dimensions of the brain, but it may have had a decided effect upon the proportion of its parts, the regions of the cerebrum devoted to intellectual activity probably increasing at the expense of the motor and sensory regions, while the convolutions may have grown considerably more complicated.
Commence on the cerebrum, and then pass to the cerebellum. If, in the examination of the spine, the practitioner finds it uncomfortable to bear in his fingers a current of sufficient strength to be distinctly felt in that part of the patient, he may use the side-sponge cup on the spine.
The superficial grey matter of the cerebrum, through the number and depth of its convolutions, attains its maximum of extent in Man. A. Left cerebral hemisphere. B. Right cerebral hemisphere. e. Scale half the diameter of the natural size. d. Backward extension of the cerebrum, beyond the cerebellum at e. f. A. Left cerebral hemisphere. C. Cerebellum. ff.
In 1861 this patient died, and an autopsy revealed that a certain convolution of the left frontal lobe of his cerebrum had been totally destroyed by disease, the remainder of his brain being intact. Broca felt that this observation pointed strongly to a localization of the memory of words in a definite area of the brain. Moreover, it transpired that the case was not without precedent.
In what sense is it reflex? How does secondary reflex action lessen the work of the nervous system? State the special functions of the nerves, ganglia, spinal cord, bulb, cerebellum, and cerebrum. State the importance of the formation of correct habits. *To demonstrate Nerve Pathways.*—A smooth board, 2x6 ft., is painted black, and upon this is drawn in white a life-size outline of the body.
The creature begins life as an infant, with its partially developed cerebrum representing capabilities which it is left for its individual experience to bring forth and modify. Lengthening of Infancy, and Concomitant Increase of Brain-Surface. The first appearance of infancy in the animal world thus heralded the new era which was to be crowned by the development of Man.
