How to move the brain with a Japanese line drawing. When does your brain perceive a still image as moving?
IN THE YouTube age it is easy to forget that artists rely on clever tricks to create a sense of motion in still images. Now brain scans show why one method of creating "implicit motion", used by an 18th-century Japanese artist, works so well. While admiring line drawings by Hokusai Katsushika, psychophysicist Naoyuki Osaka of Kyoto University, Japan, was struck by the vivid motion they convey. Instead of using blur to suggest movement, as much modern art has done since the advent of photography, Katsushika created motion by drawing bodies in highly unstable positions (see picture). This is thought to work because the brain "fills in" the effects of gravity pulling the bodies down. newscientist http://tinyurl.com/yfucwpo _______________________________________________ NetBehaviour mailing list [email protected] http://www.netbehaviour.org/mailman/listinfo/netbehaviour
