Anatomical localization of the electrode clusters along the posteroanterior axis. Electrodes were digitized and coregistered with the subject's magnetic images. Electrodes of the RI (see Fig. 4) and F/O index (see Fig. 5) are included. Average ± SE Talairach coordinates are indicated for 35 subjects. The corresponding lobe, gyrus, and Brodmann area were detected using the Talairach Client (Lancaster et al., 1997, 2000). The range (in millimeters) refers to the distance of the nearest gray matter area with respect to the coordinates.
