The Arris and Gale Lectures on the Neurology of Vision

Abstract

THE two lectures delivered by Mr. Parsons in the spring of last year before the Royal College of Surgeons deal with some points on the neurology of the eye which are of extreme interest. The first lecture lias for its subject the course of the afferent impulses from the retina to the central nervous system, and their final distribution in the cerebral cortex. Since the delivery of these lectures there have been several important contributions to this latter subject. The case of Dr. Beevor and Dr. Collier, reported in the summer number of Brain, seems to go conclusively against the more restricted visual area for which Henschen argues. In this case, despite the fact that the lingual lobe, the depths of the calcarine fissure, and the lower cuneal lobe were all affected, the restriction of the field of vision was simply quadrantic. The truth seems to be that the limits of the visual cortical area correspond to the limits of the layer of Gennari, and that this varies markedly in its relations to the surface in different cases.
