Lag normalization in an electrically coupled neural network

Moving objects can cover large distances while they are processed by the eye, usually resulting in a spatially lagged retinal response. The authors identified a network of electrically coupled motion–coding neurons in mouse retina that act collectively to register the leading edges of moving objects at a nearly constant spatial location, regardless of their velocity. These results reveal a previously unknown neurophysiological substrate for lag normalization in the visual system.
