Experiments on the section of the glossopharyngeal and hypoglossal nerves of the frog, and observations of the alterations produced thereby in the structure of their primitive fibres.Phil. Trans., 140, 423-29, 1850.The “law of Wallerian degeneration”. The experiments recorded in the above paper were the starting-point of the neuron theory. Waller showed that if glosso-pharyngeal and hypoglossal nerves are severed, the outer segment, containing the axi cylinders cut off from the cells, undergoes degeneration, the central stump remaining intact for a long period. From this he inferred that nerve cells nourish nerve fibers. Subjects: NEUROSCIENCE › NERVOUS SYSTEM › Peripheral Nerves / Nerve Impulses Permalink: historyofmedicine.com/id/2196 |
