Linking form and motion in the primate brain.
Understanding dynamic events entails the integration of information about form and motion that is crucial for fast and successful interactions in complex environments. A striking example of our sensitivity to dynamic information is our ability to recognize animate figures by the way they move and infer motion from still images. Accumulating evidence for form and motion interactions contrasts with the traditional dissociation between shape and motion-related processes in the ventral and dorsal visual pathways. By combining findings from physiology and brain imaging it can be demonstrated that the primate brain converts information about spatiotemporal sequences into meaningful actions through interactions between early and higher visual areas processing form and motion and frontal-parietal circuits involved in the understanding of actions.
