Abstract

We perceive the visual world without a lag despite substantial neuronal delays in phototransduction and subsequent neuronal transmission. Interacting with moving objects-predators, prey, or even the tennis ball approaching your racket-depends on overcoming the visual system's lag. This is a problem of prediction, and part of the solution begins in the retina with a computation called motion anticipation. Retinal ganglion cells represent moving objects ahead of their current position along their movement direction. The circuit mechanisms of motion anticipation in the retina are reasonably well understood, and they are surprisingly generalizable to other circuits throughout the central nervous system.
