RGC Circuits in the Strike Zone

(A) A second series of RGC imaging experiments as shown in Figures 1, 2, 3, and 4 was performed, this time exclusively recording from the strike zone (SZ), which surveys visual space above the frontal horizon.

(B) Overview of dominant On and Off responses among dendrites (top) and somata (bottom) for the SZ. Dendrites n = 2,370 On, n = 624 Off; somata n = 1,312 On, n = 379 Off. Chi-square with Yates correction for On:Off distributions dendrites versus somata: p < 0.22. For details, cf. Figure 2A; for a breakdown by color, see Figures S4A and S4B.

(C) Relatively slowed central frequency tuning of SZ-UV kernels (lines) compared to the retina average of UV kernels (filled) among both On (top) and Off (bottom) kernels (cf. Figures 2K and 2L). Both p < 0.0001, Wilcoxon rank sum test, 1 tailed.

(D) Ternary spectral classification of SZ dataset (for details, cf. Figure 3). Overall, note the striking On dominance and increased presence of UV responses in this dataset.

(E) Maximum amplitude scaled average kernels of the ten most abundant spectral classes among dendrites in (D).
