Abstract

Our sensations of pressure and temperature cannot wholly be accounted for by the reactions of the touch, heat, and cold spots of the skin. For when all the nerve fibres supplying an area of the skin have been divided, sensibility to temperature, to light touch (e.g. to the touch of cotton wool), and to cutaneous pain is immediately lost; but sensibility to heavier touch (e.g. to the touch of a pin's head), and to deep-seated pain over the same area nevertheless remains. These residual sensations must be due to the preservation and excitation of structures underlying the skin, situated presumably in or around tendons and muscles the nerves of which are known to contain sensory fibres. It would seem, too, that certain other cutaneous sensations are likewise of double origin; that, in addition to the apparatus for "heat" and for "cold," demonstrated by punctate exploration of the skin, there is another nonpunctate system in the skin concerned in the development of sensations of "warmth" and "coolness." More precisely, it appears that while the response to superficially painful and to hot and cold stimuli is the functional expression of one system of cutaneous sensibility, the appreciation of light touch, warmth, and coolness, and the power of precise cutaneous localisation are the expression of another system of cutaneous sensibility. For, after injury to peripheral nerve fibres, stages occur during recovery from which one of these two systems is absent, while the other remains.
