Figure 4.

A and B: Mean (± SEM) latencies of the maximal LR for the TA and MG muscles for the spinal rats shown in Fig. 2. The numbers on the abscissas (1–15) correspond to the sequence of stimuli in one step cycle as shown in Fig. 2A. The latencies of the LR for a sequence of 6 stimuli during the TA burst remain relatively constant whereas the latencies for a series of similar responses in the MG increased progressively. Abbreviations, same as in Fig. 1.
