Figure 4.

A, B, Mean ± SEM latencies of the maximal LR for the TA and MG muscles for the spinal rats shown in Figure 2. The numbers on the abscissas (1–15) correspond to the sequence of stimuli in one step cycle as shown in Figure 2A. The latencies of the LR for a sequence of six stimuli during the TA burst remained relatively constant, whereas the latencies for a series of similar responses in the MG increased progressively. Abbreviations are the same as in Figure 1.
