Temperature dependency of the chemical responses of the polymodal receptor units in vitro.
Thermal effects on chemical responses of polymodal receptors were studied using in vitro testis-superior spermatic nerve preparations excised from anesthetized dogs. Unitary discharge rates of the polymodal receptors responding to bradykinin and hypertonic NaCl solutions were found to be dependent on the temperature: the higher the temperature, the greater the discharge rate induced, although the temperature itself was mostly subthreshold to activate the receptor.
