Group Average FCZ traces. Group average (n = 8) traces recorded from electrode site FCZ. Top row traces recorded from right hand (RH) dominant group; Bottom row traces recorded from left hand (LH) Dominant group. Left column represents movement performed with the non-dominant hand, right column movement performed with the dominant hand.
