[Relationship of spontaneous locomotor rhythm and locomotion].
After decerebration at the pons Varolii level and the spinal cord section at Th10, spontaneous alternating movements occurred with a locomotor rhythm in the cat forelimbs and smoothly transmitted into stepping when a treadmill was started. The duration of EMG burst in m. triceps brachii and the cycle duration during the spontaneous locomotor rhythm depended on the forelimbs position. Their values were maximal when the limbs were protracted and minimal in retracted limbs. The cycle duration of the stepping movements in a "slow" treadmill was longer in the preparations whose spontaneous cycle duration was longer. Duration of the stepping cycle was no longer than that of spontaneous cycle when the forelimbs were in the middle position.
