| Abstract(in English) | Using fMRI, the internal mechanism involved in object recognition from non-canonical viewpoints was examined. We used a passive observation task and found several brain areas activated more strongly in the non-canonical viewing condition compared to the canonical viewing condition. It was found that the fusiform gyrus and posterior part of inferior temporal cortex (BA 19/37) are involved in the processing of shape information. On the other hand, posterior parietal cortex (BA7), mainly the superior parietal lobule, and premotor cortex (BA6/9,44) are involved in visuospatial processing and accessing sensorimotor knowledge. These results might indicate that recognition from non-canonical viewpoints is accomplished using functional properties of the object, such as which part of the object is suited as a handle. |
