  We analyse the potential effects of lateral connectivity (amacrine cells and
gap junctions) on motion anticipation in the retina. Our main result is that
lateral connectivity can-under conditions analysed in the paper-trigger a wave
of activity enhancing the anticipation mechanism provided by local gain control
[8, 17]. We illustrate these predictions by two examples studied in the
experimental literature: differential motion sensitive cells [1] and direction
sensitive cells where direction sensitivity is inherited from asymmetry in gap
junctions connectivity [73]. We finally present reconstructions of retinal
responses to 2D visual inputs to assess the ability of our model to anticipate
motion in the case of three different 2D stimuli.
