耳蜗核神经元的简化现实性模型

SIMPLIFYING REALISTIC MODEL OF NEURONS IN THE COCHLEAR NUCLEUS

采用我们以前提出的简化现实性神经网络模型［１］的一种修正形式，通过选定适当的参数，仿真了耳蜗核的类初级细胞（Ｐｒｉｍａｒｙ－ｌｉｋｅｃｅｌｌ），梳状反应细胞（Ｃｈｏｐｐｅｒｒｅｓｐｏｎｓｅｃｅｌｌ）以及给刺激反应细胞（Ｏｎｓｅｔｒｅｓｐｏｎｓｅｃｅｌｌ）对短纯青刺激的刺激后时间直方图。并通过分析参数配置和仿真行为的对应关系，指出模型在生理学上的合理性。

Using a modified version of our previously proposed simplifying realistic model with properly selected parametets, we simulate the poststimulus time histograms of the primary-like cell, chopper response cell and onset response cell in the cochlear nucleus to tone burst. The physiological reasnability of the model was discussed with an analysis of parameter settings and corresponding behaviour of the model.
