Figure 3. Target location specificity of the saccade planning map in parietal cortex.
The total number of active voxels varied among individuals (n = 19), thus the percentage of total voxels is presented. (A) Saccade Planning Map Specificity. The vast majority of significantly active voxels during the Saccade Planning Task were responsive to only one target location, with all other combinations of target location preferences representing less than 30% of the total number of voxels. No hemispheric differences existed. (B) Distribution of Preferred Single Target Map Locations in Saccade Planning Map. Voxels from the far left two columns in (A) were divided by preferred target location. All target locations were represented in both hemispheres.
