  1. The SI-BCI with the significant better performance is shown in order to compare it against its SD-BCI counterpart, for all the 3 tested conditions (LEFTMI, RIGTHMI, and REST). The mean and standard deviation (in parenthesis) for the best SI-BCI was repeated of the %ACC showed in Table  3. The performance of the SD-BCI was statistically significant better (*p < 0.05) than the performance of SI-BCI only in the cases with an asterisk.
