Image processing: how the retina detects the direction of image motion

Curr Biol. 2007 Jan 23;17(2):R63-6. doi: 10.1016/j.cub.2006.12.013.


In the retina, the beautifully symmetrical 'starburst' amacrine cells interact with each other in a way that creates asymmetrical responses to moving images at their dendritic tips. This computation, occurring in a retinal interneuron, is a foundation of the directional signals transmitted by the retina to the brain.
