Abstract

In summary, two- stroke apparent motion is a robust, vivid impression of unidirectional motion created by alternating
just two pattern frames, with a blank IFI at alternate frame transitions. It can be used to probe the properties of the underlying neural processes that encode retinal motion. A computational model of motion detection based on spatiotemporal energy can explain the effect, provided that its parameters are set to give a biphasic temporal response and a slightly imbalanced spatial response.
