Quantitative 2D maps of metabolic activity in the STs. A, Lateral view of a monkey brain with an unfolded STs and a schematic illustration of two horizontal sections at the levels indicated in the brain drawing. In the sections, points a and d correspond to the crown of the upper bank, points b and e correspond to the anterior tip of the fundus (used for alignment), and points c and f correspond to the crown of the lower bank. As, Arcuate sulcus; Cs, central sulcus; IPs, intraparietal sulcus; Ls, lunate sulcus. The grayscale bar indicates LCGU values (micromoles per 100 g per minute). B, Average STs map from the two hemispheres of the Cf monkey. The MC is demarcated by white lines. A, Anterior; D, dorsal; P, posterior; V, ventral. Letters a–f correspond to those in A. C, STs map from the monkey executing visually guided horizontal saccades. D, STs map from the monkey executing visually guided oblique saccades. E, Average STs map from the two hemispheres of the Cd monkey. F, STs map from the monkey executing memory-guided horizontal saccades. G, STs map from the monkey executing memory-guided oblique saccades.
