Figure 1.

Waveform (top), amplitude envelope (red line), and spectrum (bottom) are shown separately for an example stimulus from the original study (left, courtesy of Benedict Ng), and also a spoken German sentence for comparison (right, “Der Minister hat während der Sitzung in der Hauptstadt den Sprecher getroffen und das Ergebnis berichtet.”). In contrast to the temporal regularity contained in the sentence material, the example stimulus possesses no temporal regularity by which neural oscillations could be entrained. (a.u., arbitrary units).
