Discharge frequency [impulses per 2 seconds; (Imp/2 s)] of group III (panel A) and group IV (panel B) muscle afferents recorded from dorsal root before, during, and after locomotor exercise evoked by electrical stimulation of the mesencephalic locomotor region in decerebrate cats. The horizontal bar denotes the exercise period. Note the immediate increase of both group III and IV locomotor muscle afferent discharge at the onset of exercise and the maintained response until the exercise is terminated. From Adreani et al. (1).
