[Activity of afferent neurons after thermal stimulation of the skin of the cat forelimb].
The activity of 97 fibers of dorsal roots of lower cervical and upper thoracic segments of the spinal cord was studied in adult cats. The conduction velocity of afferents from skin receptors in respect to mechanical and temperature sensitivity was measured. All temperature-sensitive units appeared to be mechano-sensitive as well. The level of spontaneous activity and the conduction velocity of the units were defined by temperature sensitivity. The reaction parameters seem to depend on morphological properties of the skin receptors.
