From the careful analysis of the nervous symptoms in a very large number of cases of visceral disease and of lesions of the peripheral nerves and spinal cord, a group of English neurologists has recently made important additions to our knowledge of the cutaneous sensations, their peripheral nerves and central conduction paths.1
It appears that the afferent nerves of general sensation are very much more complex than has hitherto been supposed. We may consider these pathways in three sections: (1) the peripheral division, carrying the impulses to the surface of the spinal cord; (2) the intraspinal division, and (3) the cerebral division. The limits of the peripheral division do not coincide with those of the peripheral neurone. The justification for this treatment lies in the observed character of the sensory disturbances in the central and peripheral courses of the path, peripheral lesions producing a wholly different type of symptom-complex
