摘要

在嗅觉神经系统的信号传导过程中，僧帽细胞同步振荡活动模式的变化对于嗅球的编码与解码是十分重要的。为了研究颗粒细胞和球旁细胞如何影响僧帽细胞的同步发放，构造了僧帽细胞、颗粒细胞和球旁细胞这三种细胞的动力学模型，通过数值模拟得到了这三种细胞的发放模式。并通过构建网络模型，比较了各种不同细胞和在网络条件下它们之间的发放的差别。最后分析僧帽细胞群的同步运动，发现颗粒细胞和球旁细胞的抑制性作用促进了僧帽细胞的同步性。

Abstract

During the process of signal transducing in an olfactory nerve system, the change of synchronous oscillatory kinematic pattern of mitral cells(MCs) is very important for coding and decoding in the olfactory bulb.To study how the granule cell(GC) and periglomerular cell(PGC) have influenced the synchronous oscillatory kinematic pattern of mitral cells，a dynamical model for these three kinds of cells including mitral cells, granular cells and periglomerular cells was set up.Through numerical simulations, the firing patterns of the three kinds of cells were got. Then a network model for the olfactory bulb was set up for comparing the difference between the firing patterns of different cells and the difference between the conditions of with and without network. In addition, the synchronization kinematics of MCs was analyzed, and it is found that the inhibitory effect of GC and PGC contributes to the synchronization kinematics of MCs.
