Figure 5.

Data from five subjects. Grand average waveforms of ERPs for the conditions of movement observation (OBS) and of displacement of a diode light (LIGHT). The visual stimulus was a ring device worn on the observed person's right hand. The waveforms refer to the main frontal (F3, F4), central (C3, C4), parietal (P3, P4), and occipital (O1, O2) electrode sites of both hemispheres. The grand average waveform of the EMG activity of the observer during the movement observation (OBS) is represented.
