Figure 4

The mechanism of motion anticipation and the role of gain control. The figure illustrates the bipolar anticipation time \(\Delta _{B}\) without lateral connectivity. We see the response of OFF BCells with gain control to a dark moving bar. The curves correspond to three cells spaced by \(450~\mu \text{m}\). The first line (a) shows the linear filtering of the stimulus corresponding to \(V_{\mathrm{drive}}(t)\) (Eq. (1)). Line (b) corresponds to the threshold nonlinearity \({{\mathcal {N}}}_{B}\) applied to the linear response; (c) represents the adaptation variable (16), and (d) shows the gain control time curse. Finally, the last line (e) corresponds to the response \(R_{{B}_{i}}\) of the BCell. The two dashed lines correspond respectively to \(t_{B}\) and \(t_{B_{A}}\), the peak in the response of the (purple) BCell without pooling
