Modeling Neurovascular Coupling from Clustered Parameter Sets for Multimodal EEG-NIRS

Figure 6

(a)–(d) show results from fitting gamma transfer functions to 4 EEG-NIRS datasets or epochs, each of which corresponds to a pulse period including 5 s of pre- and poststimulus interval. The EEG IMF1 envelope (blue), low pass filtered NIRS HbO (red), the estimated NIRS HbO (purple), and the pulse duration (green) are shown in each plot.
