David E. K. Ferrier, William Turner · Proceedings of the Royal Society of London · 1898
Abstract The primary object of the research has been to elucidate by the aid of destructive lesions, and the study of the consecutive degenerations, the tracts by which impressions of general and special sensibility are conveyed to the cortex of the brain. For this purpose, the cortical area, supposed to be the sensory centre under consideration, was extirpated; and, secondly, the nerve, tract or primary ganglionic structure connected therewith was divided or destroyed. In this way strands of degeneration w^ere induced, in due course, of cortical afferent or efferent nature, revealed by the osmium-bichromate method of Marchi.
