  1. Note: For each patient two rows of results are provided. The results (in italics) in the second row were obtained based on the total number of trials (i.e., including the rejected trials), where the empty table cells indicated that no trial was discarded in this run. For the four healthy subjects, no trials were discarded. Accuracies with significance (p < 0.05) are highlighted in bold
