Publisher's Synopsis
Excerpt from Annual of the Universal Medical Sciences, 1894, Vol. 2
The dog, although having his entire cerebrum removed, re tained the greater part Of those faculties which in man emanate essentially from the cerebrum. The deductions from this experi ment are, however, applicable only to the dog and other lower animals, and not to man, in Whom loss Of the cerebral tissue to the same extent would unquestionably produce total abolition of all these faculties and almost certain death. The cortex is, as Edinger states, a centre superadded to the deeper ones, which is of greater importance the higher we ascend in the animal scale. The facts Of comparative anatomy prove this, destruction Of cerebral tissue producing only temporary loss or impairment Of function in dogs, a more permanent'loss in monkeys, most decided in the anthropoid ape, while in man such loss is followed almost invariably by de cided and persistent impairment in corresponding function, in pro portion to the extent Of destruction. Clinically and pathologically Edinger finds, in general paralysis Of the insane, a condition in man analogous in effect with decerebration in the dog, the final result in both cases being deep imbecility; the symptoms progress ing in severity in a ratio to the advancement Of the lesion deeper and deeper into the cortex.
