Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1881 edition. Excerpt: ...the median course of the convolution the half turned towards the longitudinal fissure is uninjured, the uninjured portion stretching from the sigmoid gyrus to within about one cen View of right hemisphere, from lateral aspect. The outline of the lesion recognized as in the last figure. timeter of the posterior limit of the cerebrum. The superior convolution is the least injured of the four external convolutions; all the portion within the median longitudinal fissure is untouched, the prolongation of this intra-marginal portion of the first convolution on the surface of the cerebrum facing the cerebellum is also uninjured except for a short distance in its upper portion as it curves out of the median longitudinal fissure. The extra-marginal division of the first convolution is affected in the last centimeter of its course, with the exception of a small portion bounding the median longitudinal fissure; anteriorly rather more than the outer half of the sigmoid gyrus is affected, the injury being still more extensive in the anterior curve of the sigmoid gyrus. It will require closer observation than I have as yet been able to give in order to determine the depth of the injury at the various parts of the different convolutions. My preliminary observation of successive transverse sections of the brain lead me to think that the following is the state of things: --Underlying the actual lesion there is, generally speaking, only a very small amount of grey matter left. Superior Convolution.--Of this convolution the outer half of the sigmoid gyrus has suffered most; in the posterior part of the anterior limb nearly the whole of the grey substance is destroyed; in the posterior limb the grey substance has been entirely removed, except possibly a small portion..show more
