EEG time course transitions to regressors. A. Mean-scaled EEG power waveform time courses for two selected frequency bands, alpha and beta1. B. Effect of hemodynamic response function (HRF) convolution with EEG power time courses. C. Absolute intensity time course for one selected microstate. D. Effect of HRF convolution with normalized microstate time course. HRF convolved time courses (B, D) are used as the final regressors for EEG informed fMRI analysis.
