[Organization of the electrical activity of different groups of muscles in rats during locomotion].
The EMG was recorded from the knee synergical group of muscle in the phase of leg move during locomotion in rats. The correlation analysis of the EMG epochs and the pauses in muscular activity respective to the moments of onset and termination of the leg move phase divided it into three independent elements: rise of the leg, maintaining of the leg over support, and stepping on the support. This suggests possible existence of three independent intraspinal subprograms which in different ways organize the work of a single group of muscles during each element of seemingly such a simple movement as the leg move during stepping.
