Figure 8: Clustered EEG segments.
From: ZuCo, a simultaneous EEG and eye-tracking resource for natural sentence reading

(a) FRPs of electrode Cz, clustered by duration of the fixation. (b) Each horizontal line represents the mean of the current and 50 adjacent EEG epochs, segmented on fixation onset. Segments are ordered by fixation duration (top: shortest fixation, bottom: longest fixation). Color represents the amplitude of the signal in microvolt.
