Book excerpt: Excerpt from Edinburgh Medical Journal, 1894, Vol. 39: Part II It is interesting to look back upon the gradual evolution of knowledge regarding the various form of aphasia, and to note the views that at different times have been held regarding the causa tion of agraphia. At first, the possibility of the existence of a special centre for the memories of the movements of writing seems scarcely to have been contemplated. The agraphia which was found to be so common an accompaniment of aphasia was supposed to be simply a necessary consequence of it. It was recognised as unreasonable to expect that words could be written, if, owing to amnesia verbalis, they could not even be remembered. We have already seen that opinion, in the present day, is coming round to this old view; which is now held to be a sufficient explanation of the agraphia in a great number of the cases presenting that symptom, though it is not supposed to be the proper explanation of it in all cases. The next step in the evolution was the localization by Exner, in of a special graphic-motor centre in the posterior extremity of the second frontal convolution, at D. It must he confessed that the facts adduced by Exner in favour of this localization are not very convincing; but nevertheless they afford a certain amount of evidence in favour of it. The localization proposed by Exner was accepted by various eminent writers'on aphasia; and it thus came to be the fashion, for a time, to refer the symptom agraphia, in most cases, to destruction of this centre D. Lying, as it does, in juxta position with Broca's convolution, the centre D is, indeed, in a great number of cases of lesion of that convolution, found to be involved along with it.
