Feedback controlled constant force stimuli of 4, 6 and 8 N intensities and of 120 s duration were applied to the receptive fields of cutaneous afferent fibers in the rat's tail. Two types of nociceptive units showed sustained discharges during these stimuli: “polymodal” unmyelinated C-units (MH-C units, N = 18, c.v. 0.5–0.9 m/s) and high-threshold mechanoreceptive A-delta-units(HTM-units, N=10, c.v. 1.9–11.2 m/s). In addition two classes of sensitive low threshold mechanoreceptors, SA I (N=6… CONTINUE READING
