Statistical comparison of correlations between brain activity and EOG. The computation is made from Type2 GO trials, Cue6 (action cue) versus Cue4 (direction cue), for saccades to the left (a) and to the right (b). Results for different time delays between the brain activity and EOG are shown in different columns. Yellow contours denote the statistical significance threshold of p < 0.001. Dotted magenta ellipsoid marks the classic FEF location .
