Differences in % between correlation coefficient (r) and the ratio between weights for the prediction of different walking parameters for the 6 subjects decoded under precision walking with and without eye electrode are shown. Positive values mean an increase of r and weight with eye electrode, while negative values mean a decrease of r and weight with eye electrode.
