| 摘 要： | 实验运用单纤维记录技术,观察了损伤神经起步点自发放电在改变Ca^2 ]。和veratridine作用下放电节律的变化。结果表明：在每一标本上,记录到的相同背景的自发放电在低与高Ca^2 浓度和veratridine的作用下,转化为三种不同类型的簇放电。结果提示,神经元放电的节律形式与刺激的性质相关,不同的节律形式可能携带着不同的神经信息。

| Abstract: | Firing patterns of injured nerve fibers were recorded using the single-fiber firing recording technique. Under the same background firing pattern, three types of bursting were induced separately by EGTA , veratridine or high Ca2+ ]o in the same type of nerve fibers. The results suggest that different firing patterns are related to different stimuli, which means that each firing pattern carries corresponding neural information. |
