On POz and Oz, the light blue displays the visual N1 associated with a homologous robot movement, while the dark blue displays the visual N1 associated with a non-homologous robot movement. On Fz, FCz and Cz, the full green line displays brain potentials associated with the robot homologous—tone congruent condition (RH–TC), the dotted green line displays brain potentials associated with the robot homologous—tone incongruent condition (RH-TI), the full red line displays brain potentials associated with the robot non-homologous—tone congruent condition (RnH-TC), and the dotted red line displays brain potentials associated with the robot non-homologous—tone incongruent condition (RnH-TI). (A) Topographical representation associated with homologous robot movement. (B) Topographical representation associated with non-homologous robot movement. (C) Topographical representation associated with RH-TC. (D) Topographical representation associated with RH-TI. (E) Topographical representation associated with RnH-TC. (F) Topographical representation associated with RnH-TI.
