title: [Sequence of discharge appearance in nerves to different hindlimb muscles during fictitious locomotion of thalamic cats].
abstract: The sequence of discharges in nerves to 22 hindlimb muscles during fictitious locomotion was investigated on immobilized thalamic cats. It is shown that for most hindlimb muscles the central locomotor program is rather simple and consists of alternating activation of flexors and extensors. A conclusion is made on the existence of interneuronal flexor and extensor centres in each half of the spinal cord, working in turns during locomotion. More complex discharges were recorded from the nerves to Edb and Per. tert. and also from the nerves to biarticular muscles (St, P. bic., Ten.). It is suggested that motoneurons of these muscles are connected to the flexor and extensor centres in a more complex way.
