Methods:Refering to Sawyer"s "The rabbit diencephalon in stereotaxic coordix nates,putting grass microelectrodes into P2-5,L3-6,H6-9 of the HPC in 2 μm/s by SN-2 to induce discharge of neurons.

The aim of this paper is to suppress negative effect of noise on complex firing patterns of neurons and extract deterministic dynamical relationship underlying irregular interspike intervals. We first give a brief introduction to ISI data to be analyzed. Then a simple nonlinear noise reduction method based on chaos theory is presented. The method is finally used to analyze ISI data both from a theoretical model and experiments.

围绕如何来消除神经元峰峰间期序列中随机噪声影响从而提取出决定不规则性的确定性动力学关系这个问题，本文首先简要介绍峰峰间期序列样本的制备，然后着重讨论一个简单可行的混沌时间序列降噪方法的原理和算法实现，最终将该方法运用到神经元放电活动数值模拟和实验记录到的峰峰间期时间序列样本分析中。

The intensity of pulse noisy pixels significantly differs from adjacent pixels of image. The de-noising will be accomplished by modifying the intensity of the noisy pixel according to the firing patterns of adjacent neurons of PCNN. At last, this dissertation suggests a new kind of filter for de-noising pulse noise based on the PCNN and median filter. It is very simple, and the simulation experiment of the image processing shows that the de-noising effect is much better than neighborhood averaging method and median filter.

一般脉冲噪声点与其所在图像像素灰度值之间相关性很差，而PCNN脉冲耦合神经网络能使相似神经元同步激发；这就决定亮点脉冲噪声像素对应神经元会在其区域所在相邻神经元中首先激发，为此结合中值滤波，我们提出了结合PCNN脉冲耦合神经网络和中值滤波的混合滤波新算法，理论分析和实验证明，该方案在滤除噪声的同时，比常规中值滤波更有效地保持了图像的高频细节信息。
