The Contribution of Visual Area V5 to the Perception of Implied Motion in Art and Its Appreciation

Does V5, a brain region involved in the perception of movement, contribute to the aesthetic appreciation of artworks that depict movement? In the study under discussion, the authors asked participants to view abstract and representational artworks depicting motion. While they judged the sense of motion conveyed by the artworks and how much they liked them, the authors delivered transcranial magnetic stimulation (TMS) over V5. They found that TMS over V5 reduced the sense of motion participants perceived and reduced how much participants liked the abstract paintings. These results show, first, that V5 is involved in extracting implied motion information even when the object whose motion is implied is not real. Second, they show that V5 is involved in extracting implied motion information even in the absence of any object, as in the abstract paintings. Finally, they show that activity in V5 plays a causal role in the appreciation of abstract art.
