    Abstract:
    In anaesthetized cats the responses of low- and high-threshold mechanosensitive C-fiber sensory units (MSU) in n. saphenus to close-arterial injection of potassium ions in subnoxious and noxious concentrations (SC and NC) have been studied. Two groups of high-threshold MSU were found: 1) MSU excited by K+ in NC only and 2) MSU responded to K+ both in SC and NC. The data suggest the nociceptive role of high-threshold MSU in contrast to low-threshold MSU. The possibility is discussed of a differentiation between subnoxious and noxious stimuli by a portion of high-threshold MSU. The characteristics of firing of high-threshold MSU are given which correlate with their excitation by noxious and subnoxious chemical stimuli.
