Abstract : The responses of specific cold-sensitive afferents and cold-sensitive mechano-receptors were recorded from rat pudendal nerve. A local infiltration of ouabain into the region of the afferent terminals caused a dramatic increase in discharge at warm temperatures without significant effect on discharge in the cold. These results suggest that an electrogenic sodium pump is the generator potential mechanism imparting cold sensitivity. (Author)
