| Abstract(in English) | Early visual areas (EVAs) have quarter visual field (VF) representations. Hence, imprints formed by visual objects on the cortex are often different from what they appear in VF. We have asked whether EVAs contribute to the integration of split VF. Using 1.5T fMRI, five subjects were scanned. Stimuli were presented with a block paradigm. ROI were confined to the regions which retinotopically represented the stimuli. We found that fMRI responses evoked by the stimuli presented over horizontal/vertical meridians were higher than those for the others, even in VI, V2, and V3. It is suggested that EVAs play an important role in integrating visual information over horizontal/vertical meridians. |
