【摘要】 在大脑皮层中,功能柱是基本的功能性单元。本文首先介绍功能柱的结构和功能, 然后根据皮层中功能柱的生理特性,简化构造一个基于神经元的微柱模型,通过数值模拟研究微柱中神经元的电位发放特性。从仿真结果可以看出,皮层中功能柱中神经元呈现丰富的发放模式,微柱内输出层神经元出现了同步发放现象,同时,微柱内神经元发放的 ISI 的图像也产生了分岔。更多还原

【Abstract】 In the cerebral cortex,the column is considered as basic functional unit.The model structure and it’s function of the minicolumn are introduced in this paper.Based on the physiological characteristic of neurons,we simplify construct a minicolumn model of a cerebral cortex,and study the spike property of neuron in minicolumn on the method of numerical simulation.The simulation results show that the neurons come rich spike activities and the synchronous phenomena of the input layer neurons in minicolumn can be observed.In the final,the images of ISI in minicolumn neuron produced bifurcation phenomena.更多还原
