Research Abstract

We used functional magnetic resonance imaging (fMRI) to investigate integration of visual information of biological motion (BM) and background motion visual motion (BVM). We found that the left V1 showed changes in neural activity depending on the specific combination of direction coherence of BVMs and BMs. This finding provides evidence for cortical integration of visual information induced by a BM and visual information on direction coherence of BVM .
We also found that the left anterior superior temporal sulcus showed changes in neural activity depending on the specific combination of velocity of BVMs and BMs. This finding provides evidence for cortical integration of visual motion information induced by a BM and visual information on velocity of BVM.
