Dynamic Predictive Coding By The Retina, Nature
 









Excerpts: Retinal ganglion cells convey the visual image from the eye to the
brain. They generally encode local differences in space and changes in time
rather than the raw image intensity. This can be seen as a strategy of
predictive coding, (...). Yet animals encounter many environments with visual
statistics different from the average scene. Here we show that when this
happens, the retina adjusts its processing dynamically. The spatio-temporal
receptive fields of retinal ganglion cells change after a few seconds in a new
environment.
