Figure 3.

Phase characteristics of forelimb-related RNNs (A–C) and hindlimb-related RNNs (D–F). A, D, Phase distribution of bursts of individual RNNs in the tilt cycle, with the preferred phase indicated (empty circles). The burst of activity of each neuron is presented in black only one time in the cycle. Neurons are rank ordered according to their preferred phase. Filled circles on the right indicate antidromically responding neurons. B, E, Percentage of RNNs with preferred phases in different parts of the cycle. C, F, Percentage of RNNs, which were active simultaneously in different phases of the cycle.
