Zusammenfassung
Using functional magnetic resonance imaging, we compared responses during visually guided saccades with those evoked during memory-guided saccades, in which participants executed saccades to remembered locations. Eye movements were recorded in the magnetic resonance tomograph. Significantly stronger activation during memory-guided saccades was observed in the posterior portion of the right inferior frontal gyrus, in the left inferior frontal eye field, in the posterior parietal cortex, as well as in the right posterior superior temporal gyrus. The posterior part of the dorsal anterior cingulum and a small voxel cluster in the dorsolateral prefrontal area, anterior to the left inferior frontal eye field, were only active in the memory-guided condition.
