Experiment 3B: motor imagery. Group-average, rectified HBR waveforms (left) and group-average HBR amplitudes (right, AUC, mV × ms) in the static condition corresponding to α1 (blue dotted line and blue empty column) and α3 (red dotted line and red empty column), and when participants were asked to imagine to move the forearm from the far to the near position (α1 to α3, red straight line and red column) and from the near to the far position (α3 to α1, blue straight line and blue column). Error bars indicate standard error. **p < 0.01.
