[The role of low-threshold tactile skin afferents in rats in the receptor response to mechanical damaging exposure].
Receptor units (RUs) of the Wistar rat foot skin only responded to a dynamic phase of mechanical adequate and nociceptive stimuli. Most of the low-threshold RUs only responded with a single AP. The RUs which developed changes in the response latency as well as an increase in the AP amplitude and duration, constituted a special group. The mechanism of the skin low-threshold afferents participation in perception of both tactile and damaging (nociceptive) stimuli, is discussed.
