Cross-Modal Audiovisual Modulation of Corticospinal Motor Synergies in Professional Piano Players: A TMS Study during Motor Imagery

Figure 2

Mean MEPs’ peak-to-peak amplitude for each chord (a) and muscle (b) expressed as percent change from baseline. (a) Motor imagery of a 9^th interval triad chord produced a significant increase in MEPs’ amplitude with respect to motor imagery of a 10^th interval chord. (b) APB muscle showed greater facilitation than ECD and FDS. Similarly, ADM showed increased corticospinal excitability when compared to ECD. Bars denote standard errors. Asterisks indicate significant differences.
