Figure 2.

Spectral profile of stimulus induced activity and results of the contrast of left vs. right sensors. (A) Time-frequency representation of the activity in response to action observation. Spectral activity was averaged across left and right sensors. Activity is presented as relative change to baseline (−500 to −100 ms). Red colors indicate increased activity relative to baseline, blue colors decrease of activity. (B) Time-frequency representation of the statistical comparison of the lateralization index (right vs. left facing actions) in right vs. left sensors of interest. 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.
