It may be said that the trunks of the ferns, which, like the monocotyledons, are enlarged by the remains of the petioles, decay from the circumference to the centre; and that, deprived of the cortical organs through which the elaborated juices descend to the roots, they are burnt more easily by the action of the oxygen of the atmosphere.
Clinical and Anatomical Analysis of 25 Cases of Mental Disease Arising in the Fifth Decade, with remarks on the Melancholia Question and Further Observations on the Distribution of Cortical Pigments. Southard and Canavan. On the Nature and Importance of Kidney Lesions in Psychopathic Subjects: A Study of One Hundred Cases Autopsied at the Boston State Hospital.
One should note that Meige and Feindel were, in a way, on the threshold of this theory when they said that tic, like the other psychoneuroses, is due to some congenital anomaly, an arrest or defect in the development of cortical or subcortical association paths unrecognized teratological malformations.
Hamilton, of Aberdeen, claims that the corpus callosum is not a commissure, but the decussation of cortical fibers on their way down to enter the internal and external capsules of the opposite side. Profs.
This cortical or glandular substance constitutes the surface of the cerebrum, and also the surface of the corpora striata, from which proceeds the medulla oblongata; it also constitutes the middle of the cerebellum, and the middle of the spinal marrow.
This is seen in the singular fact that with a monkey or man the removal of the cortical centres makes the animal permanently blind or deaf, as the case may be, while in the lower animals such removal does not have this result, so long as the "second-level" organs are unimpaired.
When he had finished he sighed deeply and said: "I am sorry to find that you are suffering from a disturbed balance of the altruistic and the egotistic cortical impulses; it is doubtless due to the intensive demands made upon the creative potential before you were completely recovered from the sub-normal psychosis due to the gas attack in the potash mines."
But the fact is, that it's the accidents ov the sperits too that's in it, and the reality's passed out through the cortical spacies, as you say; for, you may have observed, we've both been in real good sperits ever since the cork was dhrawn, and where else would the real sperits come from if they wouldn't come out ov the bottle?"
It is composed of two substances, a white fibrous substance which forms the internal portion and a gray, cortical tissue which forms the external layer. This gray substance lies in folds or convolutions, the furrows or sulci, dipping deeply into the interior of the brain.
This is certain, that it is in the head, since the head is the seat where the understanding thinks, and the will intends; and in front in the face of the head are man's five sensories, receiving life from the soul alone which resides in the head; but in what particular part of the head the soul has its more immediate residence, I dare not take upon me to say; yet I agree with those who fix its abode in the three ventricles of the brain, sometimes inclining to the opinion of those who fix it in the corpora striata therein, sometimes to theirs who fix it in the medullary substance of each brain, sometimes to theirs who fix it in the cortical substance, and sometimes to theirs who fix it in the dura mater; for arguments, and those too of weight, have not been wanting in the support of each of these opinions.
