Study of the activity of receptors with nonmyelinated fibers during heat exposure of the hairy cat skin

: A nerve activity in heating of the cat hairy skin was studied in acute experiments in order to find out if the C-receptors take part in peripheral coding of heat information. An integrative cross-correlation technique was used to analyse neurograms in the real time. No C-afferent activity was found in the thermal stimulation up to 41 degrees C of the hairy skin.
