Activation extent was slightly higher for the right cerebrum than the left. In

both sides of the cerebrum, the occipital lobe demonstrated the greatest activation, followed by the frontal and parietal lobes. In both sides of the occipital lobe, the cuneus demonstrated the highest activation, followed by the lingual gyrus and middle occipital gyrus. Activation in the right frontal lobe was Inhibitors,research,lifescience,medical concentrated in the middle frontal gyrus, an area housing a large portion of the dorsolateral prefrontal cortex. In the cerebellum, activity was greatest in the posterior lobe, with the declive being the gyrus of highest activation on both sides. Table 1 Extent and mean z-statistic for the ROIs of greatest activation. Table ​Table22 shows the results of the quantitative analysis for the 30 ROIs of greatest deactivation extent. Inhibitors,research,lifescience,medical Deactivation extent was higher by nearly a factor of 2 in the left cerebrum compared with the right. In both sides of the cerebrum the frontal lobe demonstrated the greatest deactivation, followed by the parietal, temporal, and limbic lobes. The foci

of deactivation within the lobes were not as homogeneous between hemispheres as compared with the activation foci, although the limbic lobe did demonstrate a focus in the cingulate gyrus on both sides. Table 2 Extent and mean z-statistic for the ROIs of greatest deactivation. Volume Inhibitors,research,lifescience,medical renderings of the

group activation (orange) and deactivation (blue) results are shown in Figure ​Figure3.3. On the left, highly homogenous activation of the occipital lobe Inhibitors,research,lifescience,medical is evident, as is activation in the cerebellum. Deactivation is also evident on both sides of the parietal lobe in the angular gyrus, inferior parietal lobule, and precuneus, and extending down Inhibitors,research,lifescience,medical into the temporal lobe in the superior temporal gyrus and middle temporal gyrus. On the right, additional activation can be seen in the frontal lobe at the AG14699 precentral gyrus and medial central gyrus, and transitioning into the cingulate gyrus. Additional deactivation is present throughout the medial frontal gyrus and superior frontal gyrus. Figure ​Figure44 also shows activation results in the middle frontal gyrus of the right cerebrum.

The spatial distributions of the COMs for the three lobes of greatest extent for both contrasts were plotted using the Brainmap Slueth 2.0 program (Fox and Lancaster 2002; Fox et al. 2005; Laird et al. 2005).
