[Qualitative differences in the reactions of the spinal nerves of the frog Rana temporaria during chemical stimulation of the skin].
Studies have been made on total impulse activity in the skin nerves of the frog during application of acid solutions as well as during tactile stimulation. It was shown that the reactions to various stimuli differ with respect to their pattern and amplitude of integrated response curve which reflects changes in the frequency of total impulsation. In responses to test solutions and tactile stimulation, different units may be involved which specifically react to each of the stimuli. This specificity of single elements is also revealed during changes in the evoked total activity resulting from superficial skin anaesthesia. Possible nature of peripheral structures involved in these reactions is discussed.
