Values are mean ± SD. Successful cases, number of subjects with successful localizations (>80%); Position, coordinates of ECDs; Reactivity, sources reactivity indexes to the three stimulations RL, RT, RM, pure numbers. M20L, M20T, M30L, M30T positions computed on MEG data are reported for comparison.
