有限大小神经元细胞膜动作电位的温度效应

研究了温度对有限大小神经元细胞膜动作电位的影响．发现随着温度的增加，在相同的时间内神经元产生的脉冲数目有先增加再降低的变化．在中等面积下，平均脉冲间间隔有类似于共振的先降低，达到最小值，再增加的现象．通过计算功率谱以及由功率谱定义的卢因子,很清楚地看到β在某些温度时达到了最大值，产生了相干共振．

Effects of Temperature on the Producing of Action Potential in Finite Size of Neuron Membrane

We studied the effects of temperature on the producing of action potential in finite size of neuron membrane. It is found that with increasing temperature, the number of spikes in the same time interval first increases, and then decreases as the temperature increasing further. Under moderate membrane size, the mean inter spike interval of membrane potential first decreases, reaches a minimum, and then increases with temperature. By computing the power spectral density and defining a measure parameter, we show that under certain temperature, action potential reach a maximum, which corresponding to the coherence resonance.
