The activity of C3-C4 propriospinal neurons was recorded during "fictitious locomotion" of forelimbs in immobilized decerebrated cats with the spinal cord transected at the lower thoracal level. The neurons were identified by the antidromic responses to stimulation of the lateral funiculus in the C6 segment. Most of the neurons (70%) were antidromically activated also from the lateral reticular nucleus. The discharge frequency of most neurons was rhythmically modulated in correlation with the motoneuron activity during "fictitious locomotion", i.e. in the absence of any rhythmical signals from the limb receptors. The cooling of the rostral area of the cervical enlargement abolished both the generation of the locomotor rhythm and the rhythmical activity of the propriospinal neurons. Therefore intraspinal mechanisms controlling the forelimb activity are the main source for rhythmical modulation of the C3-C4 propriospinal neurons.
在胸段下部水平脊髓横断的固定去大脑猫前肢“虚拟运动”过程中，记录了C3 - C4脊髓固有神经元的活动。通过对C6节段外侧索刺激的逆向反应来识别这些神经元。大多数神经元（70%）也可被外侧网状核的刺激逆向激活。在“虚拟运动”期间，即没有来自肢体感受器的任何节律性信号时，大多数神经元的放电频率与运动神经元活动相关地进行节律性调制。颈膨大头端区域的冷却消除了运动节律的产生以及脊髓固有神经元的节律性活动。因此，控制前肢活动的脊髓内机制是C3 - C4脊髓固有神经元节律性调制的主要来源。
