[Perception of remote warm and cold point stimulation of different areas in human skin].
The study was made in 57 female students to investigate the verbal and temperature characteristics of the perception of remote thermo- and cryostimulation in 3 skin points, 3 mm in diameter, having different innervation, such as the back, forearm, concha auriculae. No information on the site and modality of a stimulus was given to the examinees. The mean time of thermo- and cryostimulation applied to each skin point was 40 to 300 sec. The students were found to have a right perception of the site and modality of a stimulus in the ear skin most commonly, they perceived those in the back less commonly, and in the forearm least commonly. Control studies measuring the temperature of a microarea in the forearm skin indicated that remote thermo- and cryo-stimulation caused exponential temperature changes: a sharper rise on heating and a "gently sloping" decrease on cooling.
