Topic: direction selective cells

As animals navigate and interact with their environment, the image projected on their retina is constantly moving due to both self-motion and external motion of objects. Thus understanding how the retina processes moving objects is of crucial importance. This task is made difficult by the many non-linearities present in the retinal circuit. Previous works showed that retina ganglion cells extract specific non-linear features from moving objects and send this information to the brain. For example, direction selective cells respond maximally to motion in a ”preferred” direction and not in the
