Antagonist Muscle Prefatigue Increases the Intracortical Communication between Contralateral Motor Cortices during Elbow Extension Contraction

Figure 2

Average EEG power during pre- and postfatigue elbow extension contractions. The EEG power at C3 in the alpha band and FC3, C3, FC4, and C4 in the beta band was significantly increased during postfatigue contraction compared with that during prefatigue contraction. Data are mean ± SE. Significant differences are indicated by asterisks ().
