FIG 2. Percent activation volume in each of four areas of activation in right and left cerebral hemispheres for the visually guided saccade paradigm. The regions are SEF, FEF, IPS, and PFC. The voxel numbers for each region were pooled from the activation maps of each participant. Table 3 shows that there is a corresponding significant difference (P < .02, unpaired two-tail t test) in LR for IPS between the normal group and the pAD group.
A, pAD group (n = 18). *, statistically significant difference (P < .10, paired two-tailed t test) between the volume of activation for the right and left hemispheres.
B, Control group (n = 10). *, statistically significant difference (P < .001, paired two-tailed t test) between the volume of activation for the right and left hemispheres.
