Repetitive stimulation of a dorsal root evoked stepping movements of the hind limbs of a mesencephalic cat on a moving treadmill. The step duration either a) correlated with the stimulus frequency or b) depended entirely on the speed of the treadmill. The stimulus frequency evoking walking in transmamillary preparations, which could not walk on a moving(More)
Effects of bilateral lesions of the spinal cord at the upper cervical level on the walking elicited by stimulation of the midbrain or of the spinal cord, were studied in decerebrated cats. The locomotion could be elicited after lesions of the ventral funiculus together with the dorsal part of the lateral funiculus, or of the ventrolateral funiculus only, or(More)
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(More)
Spike activity of single neurons in the upper cervical segments C2-C3 or at the brachial enlargement C5-C6 was recorded in decerebrated cats during spontaneous locomotor rhythm after transection of the spinal cord at the low thoracic level. The shortest interspike intervals in 66% of cyclically active neurons at C5 were observed during electrical activity(More)
Bilateral destruction of the medulla, interrupting both “locomotor strips,” was carried out on mesencephalic cats. After the operation walking could still be induced by stimulation of the more rostral (and also caudal) portion of the strip, although in some experiments the threshold of walking was raised. The connection of the “locomotor strip” with other(More)
During the study of locomotion of dogs on a treadmill, indications were obtained of the essential importance of interaction between the limbs in movement coordination [4]. More direct data were obtained by the use of a preparation with guided locomotion [6]. It was shown that natural reflexes from the forelimbs on motoneurons of the hind limbs, which are(More)
After dissection of the brain stem caudal to the rostral border of pons Varolii, a locomotor ability of the forelimbs was studied in cats with the spinal cord sectioned at the low thoracic level. Two groups of preparations were obtained. The 1st one was able to walk on the moving treadmill belt. The Horsley--Clarke coordinate of the dorsal border of the(More)
