Abstract

Penetration of two closely (3.2 Msec) spaced antidromic volleys in dendrites of spinal motoneurons is considered in the normal, anoxic, and postanoxic states. It is concluded that the value of the L-fraction (Lorente de N6) of membrane potential at the time of impulse conduction largely determines the extent of penetration or, in other words, the spatial decrement of dendritic conduction. The observations are pertinent to interpretations with respect to monosynaptic reflex transmission.

摘要

在正常、缺氧和缺氧后状态下，研究了两个紧密间隔（3.2毫秒）的逆向 volley 在脊髓运动神经元树突中的穿透情况。得出的结论是，冲动传导时膜电位的 L 分数（洛伦特·德·诺6）值在很大程度上决定了穿透程度，或者换句话说，决定了树突传导的空间衰减。这些观察结果与单突触反射传递的解释相关。
