Displayed are the Cz EEG-power changes (group average including the 10 participants) after control (a), olfactory (b) and trigeminal (c) stimulation. The dashed black line marks the stimulus onset. An increase in low frequency within the ROI (red square) can be observed in b and c but not in a. The scale displays EEG-power change in percent compared to the pre-stimulus interval.
