[The mechanism of skin receptor excitation during temperature stimulation]

The skin was found to contract under the cold effect, and pilomotors were contracting during stimulation of the C efferents. The pilomotors were shown to take no part in the temperature deformation of the skin. Using the colliding impulses method, the skin mechanoreceptors were shown to be activated both by contractions of the pilomotors and by the temperature deformation of the skin. The possibility to activate the skin mechanoreceptors by the temperature deformation of the skin collagen, is discussed.
