Abstract

Using the Fourier transform on a peristimulus time histogram (PSTH) to calculate spectral components of a spike train can yield erroneous spectral amplitudes. This happens because the PSTH is a function defined at discrete points in a way that conflicts with the sampling theorem.

摘要

对刺激时间直方图（PSTH）进行傅里叶变换以计算脉冲序列的频谱成分可能会产生错误的频谱幅度。出现这种情况是因为PSTH是一个在离散点定义的函数，其方式与采样定理相冲突。
