Figure 7. Overview of detection results.

Detection accuracy was measured when signals from all ECoG electrodes were used for detecting outcome (top half) and execution (bottom half) errors. For detection, we used the low frequency component (dashed line), the high frequency component (dotted line) or both frequency components together (full line). Top rows of panels show the TPR (blue lines) and FPR (red lines), while the bottom rows of panels show the normalized mutual information C_YX (black lines). Error bars show 95% confidence intervals. Different columns show results for different subjects. Detection was made using rLDA.
