Research Abstract |
Itching has been known to be conducted by unmyelinated C-fibers. Current perception threshold (CPT) obtained from stimulation ofunmyelinated C-fibers didn’t change by changing skin surface temperature, suggesting skin surface temperature might not influence CPT of unmyelinated C-fibers. Furthermore, pain threshold in rhigosis or thermoesthesia might be independent on moisture of skin surface. Therefore, it is suggested that CPT or pain threshold might be affected by temperature of moisture of skin surface.
