| Research Abstract |
We investigated the architecture of multi-synaptic top-down pathways toward visual area4 (V4) of ventral stream and visual area 5 (MT/V5) of dorsal stream, employing retrograde trans-synaptic transport of rabies virus. In addition, multi-synaptic architecture from the medial temporal lobe to V4 was also investigated. We found that frontal inputs to MT/V5 and V4 mainly arise from area 46v. In addition, we found shot-cut pathway from the hippocampus proper to V4. These results indicate that multi-synaptic architecture may provide top-down information about object recognition accomplished throughoccipito-temporal and occipito-parietal pathways.
