| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The effect of the attended visual hemifield on the brain activities in posterior parietal and occipital visual cortex was examined in order to investigate neural substrates of voluntary visuospatial attention. Our brain imaging data supported the theory suggested by the previous psychophysical study that attentional resources for left and right visual hemifield are separated. When the attention was controlled appropriately, increasing of attentional load induced asymmetric brain activities, that is, the activity increase induced by the load increase was larger when attending left hemifield than right hemifield. This result suggested it is possible that attentional resource for each visual hemifield were implemented in both hemispheres asymmetrically. |
