Fig 2. Locations of the DLPFC, FEF and IPS in one representative subject.

Executing a saccade (pro-saccade, anti-saccade) was used as an event to functionally identify the six ROIs (DLPFC, FEF, IPS in each of the two hemispheres). These regions are consistent with those localized by DeSouza et al (2003) and the Talairach coordinates are shown in Table 1.
