We introduce a two - dimensional motion model of neural system , fhn neural model . then by using of adiabatic elimination method and the presence of noise , the system becomes a special double singular stochastic system . the effects of parameter , which marks the singular degree of stochastic at singular point , on the phase transition of the fhn model is discussed when is non - integer
首先介绍了神经系统的二维动力学模型，即fhn模型，接着考虑引入乘性噪声后， fhn神经模型变为一个特殊的双奇异随机系统，研究了该系统的相变情况，同时得出了噪声强度临界值的解析表达式，着重分析了噪声的奇异性标度和噪声强度对神经细胞内电位的概率分布以及电位的平均值的影响。
