| Outline of Final Research Achievements |
The aim of this research is to establish an animal model of spatial neglect. For this purpose, we made a lesion in the right superior temporal gyrus and evaluated their behavior with a target-selection task and eye-tracking. We found that neglect-like behavior was sustained for more than 1 month after the lesion. Thus we conclude that we established an animal model of spatial neglect. We also measured BOLD activity of the same monkeys before and after the lesion and found that the functional connectivity within the attention network is reduced and recovered, which was correlated with behavioral markers of spatial neglect after the lesion.
