Cold Fiber Discharge Pattern under in Vitro Conditions: Ouabain and K+-Effects

Until recently it has only been possible to give broad descriptions of the mechanisms involved in cold receptor temperature transduction. Cold receptor responses to constant and to rapidly changing temperatures were ascribed to two temperature dependent antagonistic processes with different time constants and temperature coefficients.1 Evidence as to the nature of these processes came from studies of molluscan neurons. It was assumed that the response characteristics of cold receptors were due to the activity of an electrogenic ionic pump and to the Na-K permeability ratio, which is additionally affected by voltage and temperature dependent calcium effects.2,3,4,5
