For each FS in response to the right and left median nerve stimulation, mean position [standard error] (x, y, z) and residual variances (r.v.) across subjects of the corresponding ECD are reported. In the discrepancy columns, the discrepancy median and interquartile ranges, i.e. the values including the central 90% of the distribution [5–95 percentile] are indicated.
