"It's done even more than that," Lea said, separating the convolutions of the gray matter with her scalpel to uncover a green filament beneath. "These tendrils penetrate further back into the brain, but always remain in the cerebrum. The cerebellum appears to be untouched. Apparently just the higher functions of mankind have been interfered with, selectively.
The ganglia are grayish enlargements formed by nerve cells and supporting tissue, situated at the origin of the nerve trunk or along its course. The brain is an oval mass of nerve tissue elongated from before to behind, and slightly depressed from above to below. It terminates posteriorly in the spinal cord. The cerebrum forms the anterior portion.
Buhring relates the history of a case somewhat analogous to viability of anencephalous monsters. It was a bicephalous child that lived thirty-two hours after he had ligated one of its heads. A stroke of the knife bad severed the larynx and removed the whole mass of the cerebrum, leaving the inner aspect and base of the skull exposed.
The vast majority of movements performed by young infants are reflex acts, that is, the cerebrum, the part of the brain with which thinking is done, is not concerned with their performance.
If the viscera, and other organs of life, had been found to be the same as in Protestant bodies; if the provisions of nerves, arteries, cerebrum, and cerebellum, had been the same as we are provided with, or as the Dissenters are now known to possess; then, indeed, they might have met Mr.
It is the surplus of molecular disturbance remaining in the cerebrum and cerebellum, and reflected back and forth among the cells and fibres of which these highest centres are composed, that affords the physical condition for the manifestation of consciousness. Memory, emotion, reason, and volition begin with this retention of a surplus of molecular motion in the highest centres.
P. Pons. D.G. Dorsal root ganglia. S.G. Sympathetic ganglia. N. Nerve trunks to upper and lower extremities. The arrangement of the neurons of the spinal cord is just the reverse of that in the cerebrum—the center being occupied by a double column of cell-bodies, which give it a grayish appearance, while the fibers occupy the outer portion of the cord, giving it a whitish appearance.
In the human organism physical variation has well-nigh stopped, or is confined to insignificant features, save in the grey surface of the cerebrum. The work of cerebral organization is chiefly completed after birth, as we see by contrasting the smooth ape-like brain-surface of the new-born child with the deeply-furrowed and myriad-seamed surface of the adult civilized brain.
The next instant another pile of matches sent up a wavering flare in the gloomy, terrifying twilight. Frederick mentally cut out the young man's cerebrum and cerebellum for an anatomical examination, proceeding strictly according to the rules of dissection, as he had so frequently done in actuality.
But when my father read on, and was let into the secret, that when a child was turned topsy-turvy, which was easy for an operator to do, and was extracted by the feet; that instead of the cerebrum being propelled towards the cerebellum, the cerebellum, on the contrary, was propelled simply towards the cerebrum, where it could do no manner of hurt: By heavens! cried he, the world is in conspiracy to drive out what little wit God has given us, and the professors of the obstetric art are listed into the same conspiracy.
