Abstract
Analysis of the afferent activity in the myelinated Adetla-fibers was carried out using the modified colliding impulses method. Frequency characteristics of the orthodromic impulses pattern without any preliminary electrical stimulation of Adelta-fibers and after its application to the nerve were compared. It was found that the antidromic impulses appearing under the electrical stimulation of the nerve caused an increase in the frequency of impulses in the afferent pattern in adequate stimulation of the cutaneous receptors.
摘要
使用改良的碰撞冲动法对有髓鞘的Aδ纤维中的传入活动进行了分析。比较了在未对Aδ纤维进行任何预先电刺激时以及对神经施加电刺激后顺行冲动模式的频率特征。结果发现，在对神经进行电刺激时出现的逆行冲动，在对皮肤感受器进行适当刺激时，会导致传入模式中冲动频率增加。
