Synaptic events evoked by in lumbar motoneurons ally antidromic by stimulation of identified reticulo- and vestibulo-spinal neurons were studied in the rat. Monosynaptic actions produced by fast-conducting reticulo-spinal fibers were found in different hind-limb motoneurons innervating proximal and distal flexor and extensor muscles. Vestibulo-spinal projections contained relatively few fast-conducting fibers and produced mainly polysynaptic actions in hind-limb motoneurons. The convergence of reticulo- and vestibulo-spinal synaptic influences in different motoneurons was demonstrated.
在大鼠中研究了通过刺激已鉴定的网状和前庭脊髓神经元在腰段运动神经元中诱发的突触事件以及逆向冲动。发现快速传导的网状脊髓纤维产生的单突触作用存在于支配近端和远端屈肌及伸肌的不同后肢运动神经元中。前庭脊髓投射包含相对较少的快速传导纤维,并且在后肢运动神经元中主要产生多突触作用。证明了网状和前庭脊髓突触影响在不同运动神经元中的汇聚。
