FIGURE 2.
ROIs and SUVmean maps. First row depicts investigated ROIs covering cortical, subcortical, and white matter structures: 1, frontal cortex; 2, somatosensory cortex; 3, parietal cortex; 4, occipital cortex; 5, cingulate cortex; 6, thalamus; 7, corpus callosum; 8, cerebellar gray matter; 9, hippocampus; 10, centrum semiovale; 11, temporal cortex; 12, striatum. Amygdala and cerebellar white matter are not visible in the presented slices (MNI space, x = −4, y = 16, z = 7 mm). Remaining rows depict radioligand distribution in terms of SUV for various time points (averaged across subjects).
