Figure 10: Topographic consistency test (TCT) applied to the four within conditions of the sample data (C1: correct sentence ending day 1; F1: false sentence ending day 1; C2: correct ending day 2; F2: false ending day 2). For each condition, two graphs are shown. The upper one displays the 𝑃 value obtained by the TCT (vertical axis) and the chosen threshold (red line). The 𝑥 -axis displays the time from 0 to 1000 ms from the word onset on. The second graph shows the Global Field Power (GFP), with periods of consistent topographies marked in green. The 𝑦 -axes of the lower graphs indicate the GFP amplitude in 𝜇 V.
