摘　　要：本文介绍了一种有效提取大鼠海马锥体细胞放电信号的算法 ,即利用小波变换能将各种交织在一起的由不同频率组成的混合信号分解成不同频段的信号的特性 ,采用小波变换 ,对大鼠海马神经元放电信号进行处理 。In this paper we introduce an algorithm based on wavelet transforms(WT)which has been developed for effectively detec ting rat pyramidal cell discharge.Charactermities of WT was used to process and decompose mixed signal of different frequencies into separate signals at different bands.Then,discharge signals of interim neurocells were separated from discharge signals of pyramidal cells.Finally,discharge signals of inividual pyramidal cells were extracted.Results obtained showed that,this was a successful and effective method.
