Fig. 2. Spatial plots for simple movement (A) and tool use movement (B). The beginning of the Bereitschaftspotentials (BPs), or movement-related cortical potentials, are seen to occur in bilateral sensorimotor areas in simple movement, while it is seen to begin in the left parietal area in tool pantomime.
