Fig. 5. Surface projections (vertex, right lateral, left lateral, and right sagittal) of brain areas with a significantly decreased rCBF in the sedated (A ) and anesthetized (B ) states relative to that in the awake state, and comparisons between degrees of rCBF in these two states (C ). The relative rCBF was reduced in the parietal association cortex (consisting of the precuneus [Pcu], the supramarginal gyrus [Gsm], and the angular gyrus [Ga]) in the sedated state. In the anesthetized state, moreover, the relative rCBF in the pulvinar nucleus of the thalamus (P), the pontine tegmentum (PTgm), the posterior cingulate gyrus (PCG), the cerebellar cortex (CC), and the left dorsolateral prefrontal cortex (DLPFC) was decreased. The significant areas are described in detail in the text and listed in table 2.
