Outline of Final Research Achievements

The objective of this study was to analyze human brain activities underlying the three-dimensional object perception from visual motion especially in terms of the neural information flow between various brain regions, and also, to develop the method to evaluate individual performance in mental three-dimensional object manipulation. The results show that the three-dimensional object perception from motion relies on the cooperative engagement of higher order visual processing that takes place both in the dorsal and the ventral visual pathways located in the occipital, parietal and inferior temporal lobule. The results also indicate that the individual performance in three-dimensional object manipulation correlates with the gamma-band brain activities measured in the occipital and the parietal areas.
