Premotor cortex

Activity of cat premotor cortex neurons during visually guided stepping

Supplemental Figure 1. Example activity of a neuron during standing.

The fluctuation of the discharge of individual neurons during standing was estimated. The activity of a pyramidal tract neuron (PTN #42) during 3 sets of selected time intervals is shown. This is the same PTN, the activity of which during locomotion is shown in Figure 3.
