Figure 8. The Reversal Response Cannot Be Explained by a Classical Receptive Field Model.
(A) Response of a single cell to smooth motion (top) and reversal far from the receptive field (bottom). Peristimulus time histogram (PSTH) is shown in black, the convolution of the linear receptive field and the stimulus is shown as a dashed line, and the best fit prediction from the LN model with gain control is shown as a gray line. Model parameters as in Berry et al. (1999); τ = 97 ms; α = 360 Hz; β = 310; θ = 0.043.
(B) Same cell responding to reversals near the receptive field.
