时频分析 mne.time_frequency子模块提供了几种算法的实现,以计算时频表示,功率谱密度和互谱密度。例如,在这里,我们将使用Morlet小波为听觉时期计算不同频率和时间的感应功率。在此数据集上,结果并不是特别有用(它仅显示诱发的“听觉N100”响应);有关具有更丰富频率内容的数据集的更多扩展示例,请参见此处。 freque...

I want to robustly estimate a power spectrum from raw data. I am concerned that segments of my raw data contain artifacts. mne.time_frequency.psd_welch divides the raw data into N (possibly overlapping) windows, computes N psds, and returns the average psd. Could we add the option to re...
