ResumoCutaneous high-threshold cold receptors (HCRs) in the monkey were identified as sensitive only to cold temperatures below 27°C and not responsive to mechanical or heat noxious stimulation. Some HCRs had axons conducting in the low A-δ range while others had C fibers. The response properties of HCRs were contrasted with those of mechanothermal nociceptors, the latter believed to contribute to the sense of cold pain. HCRs with Aδ fibers may contribute to the sense of innocuous cold below temperatures to which low-threshold cold receptors are maximally responsive.
