| 摘 要： | 研究了随机更新输入的IF神经元模型的近似问题，得到了两种新的近似方案．讨论了低相关更新输入对Integrate-and-Fire模型输出的影响．对低的正相关，随着输入相关的增加，平均发放时间缩短．对低的负相关，平均发放时间独立于输入相关．

| Abstract: | The issue how to approximate the integrate-and-fire(IF) model with renewal process inputs is studied.Two novel approximation schemes are proposed.The effects of positive and negative correlations are discussed,mean firing time is a decreasing function of input correlation. For low negative correlations,mean firing time is almost independent of input correlation. |

| Keywords: | integrate-and-fire model renewal process the interspike interval correlation |
