Figure 3.

A, Binary data for the presence of significant WCS (lower plot) and significant tremor activity (upper plot) over the course of time in a representative subject. The onset of tremulous activity was at ∼60 s (Figs. 1, 2). The right side shows the enhanced period marked with a rectangle. Thereby, Δt is the difference between the onset of tremor and the begin of significant coherence. B, Boxplot of the mean time difference between tremor onset and WCS onset for the five locations of recordings within one height. Asterisk depicts the statistically significant difference of Δt between central and lateral electrodes (p = 0.049).
