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.
在固定的丘脑猫身上研究了虚拟运动期间神经向22块后肢肌肉的放电序列。结果表明，对于大多数后肢肌肉，中枢运动程序相当简单，由屈肌和伸肌的交替激活组成。得出的结论是，脊髓的每一半都存在中间神经元性屈肌和伸肌中枢，在运动过程中交替工作。从向拇短展肌和第三趾展肌以及向双关节肌肉（半腱肌、股二头肌、跟腱肌）的神经记录到更复杂的放电。提示这些肌肉的运动神经元以更复杂的方式与屈肌和伸肌中枢相连。
