Figure 5.

Topographical representation of the lateralization index and statistical comparison of lateralization index for distinct sensor sets. (A) Illustration for the early significant cluster shown in Figure 2 (275–675 ms, 12–16 Hz) and Figure 3A. (B) Same as (A), but now for the late cluster (1225–1775 ms, 22–28 Hz; Figures 2, 3B). Red colors indicate greater power for right facing actions compared to left facing actions (positive lateralization index), blue colors indicate smaller power for right vs. left facing actions. Colorbars apply to both plots. (C) Left panel: Same analysis and representation as in Figure 2B, but now separately for the more medial sensors (upper row) and for the more lateral sensors (lower row). t = 0 denotes the onset of stimulation. Red colors indicate greater lateralization index in right sensors compared to left sensors, blue colors indicate a smaller lateralization index. Results are masked to highlight significant clusters. Colorbar applies to the significant (non-masked) pixels. Right panel: Red circles indicate four sensors in the left hemisphere and black triangles indicate four sensors in the right hemisphere used for statistical analysis shown in the left panel.
