<p><b>A</b>, Experimental Y-neuron response data. <b>B</b>, Best fit to time-resolved DOG model in Eq. (4). <b>C</b>, Deviation between experimental results (A) and model results in (B). Error <i>ε</i> (cf. Eq. 1) is 0.016. <b>D</b>, Fitted values of weight parameters <i>A</i>(<i>t<sub>i</sub></i>) and <i>B</i>(<i>t<sub>i</sub></i>) for Y neuron. <b>E</b>, Fitted values of width parameters <i>a</i>(<i>t<sub>i</sub></i>) and <i>b</i>(<i>t<sub>i</sub></i>) for Y neuron. <b>F</b>, Time-resolved error <i>ε<sub>t</sub></i> (cf. Eq. 2) for Y neuron. <b>G–L</b>, Same as (A)–(F) for the X-neuron response data. The deviation between experimental results (G) and model results (H) corresponds to an error <i>ε</i> = 0.012. Note that the almost vertical lines in panels (D) and (J) signal a rapid growth of the fitted value of the weight parameter <i>B</i> to values beyond the maximum values of the y-axes. The almost vertical lines in panels (E) and (K) correspondingly signal a rapid growth of the width parameter <i>b</i>.</p
