2 . hi some of the neurons with spontaneous activities , veratridine can transform isi series to oscillation type 在有自发放电的神经元，栗芦碱可使部分神经元的isi序列转变为振荡形式。

In present study , single fibre recording in vivo from dorsal root on chronically compressed drg model was used . we analyzed the characters of isi series of oscillation firing of type a neurons induced by veratridine , an inhibitor of inactivation gate of sodium channel . so we can establish a basis for understanding the relationship between the inactivation gate of sodium channel and the firing pattern , so as to explore the relationship between the firing pattern and pain 本研究在大鼠背根节慢性压迫模型上，利用在体单纤维记录方法，观察与分析na通道失活门抑制剂藜芦碱引起受损背根节a类神经元放电isi序列发生的变化特征，为了解na通道失活门与放电型式的关系以及进一步探索放电时间型式与疼痛的关系奠定基础。
3.
Compound pattern ( 6 . 4 % ) , its scatter map of isi series displayed two or more oscillation patterns . 4 . after the bath in 1 . 8 - 3 u mol / l veratridine , touch or pressure on the l5 receptive fields could trigger some primary silent drg neurons to produce high - frequency firing , termed triggered oscillation , whose interspike intervals ( isi ) showed u - type or other types of oscillations 在部分静息神经元lsdrg浸浴壹芦碱后，触压该神经元的皮肤感受野，可以触发产生持续数秒至数十秒的高频放电，在散点图上，其isi序列形成u字形或弥散形等型式的振荡，称之为触发振荡。
