Supplementary Figure 4: Contrast-dependent effects of distal activation in the far MZ
From: Distal connectivity causes summation and division across mouse visual cortex
(a-c) Panels show the effects on the activation peak (a, n = 56), on the suppressive peak (b, n = 103), and on the overall spike count change in a 600 ms window following laser stimulation (c, n = 103). (d-f) Histograms measure the difference in normalized response between control and laser stimulation (data shown in Fig. 4g). (d) Sites with activation and suppression (n = 56). (e) Sites with suppression alone (b, n = 47). (f) The population response as a function of stimulus contrast, for sites with activation and suppression (red) and sites with suppression alone (blue). The curves illustrate the prediction based on the normalization model, using the same set of parameter values as in Fig. 3a,b.
