F-values and the corresponding FDR-corrected q-values for main effects of task precision, hand performance, and their interaction are shown for channels that exhibited significant effects after FDR correction (q < 0.05).. Oxyhemoglobin (oxy-Hb) and deoxyhemoglobin (deoxy-Hb) signals were separately analyzed.
