Lateralization analyses among the three conditions in the mu band and the beta band.

Data are shown as mean with standard deviations.
One-way repeated measures ANOVAs were employed to calculate statistical significance of time-phase under three conditions in each group.
*
The percentage of ERD areas had statistically difference compared to the same phase of P0 in each condition (p < 0.05). No statistically significant difference was found in beta band.
