Abstract

The central generation of burst activity was investigated in the buccal ganglia of Lymnaea. Eight different patterns of burst activity were generated by one or two consecutive phases of compound synaptic potentials resulting from activity of neurones. These inputs acted upon the different endogenous properties of buccal neurones such as post-inhibitory rebound and spike adaptation. Effects of synaptic inputs were reinforced by by electrotonic coupling of some buccal neurones of the same type.

摘要

在椎实螺的颊神经节中研究了爆发活动的中枢产生。由神经元活动产生的复合突触电位的一个或两个连续阶段产生了八种不同的爆发活动模式。这些输入作用于颊神经元的不同内在特性,如抑制后反弹和峰适应。同一类型的一些颊神经元的电紧张耦合增强了突触输入的作用。
