Changes in LGN-V1 gamma coherence with arousal states and visual stimulation explained by LGN gamma synchrony

(A) Histogram of pupil diameter, a measure of arousal (McGinley et al., 2015).

(B) LGN-V1 coherence for low and high arousal (n = 8 mice, p < 0.05; Wilcoxon signed-rank test).

(C) LGN-LGN phase locking for low and high arousal (n = 8 mice, p < 0.05; Wilcoxon signed-rank test).

(D) Arousal-related change in LGN-LGN spike-field locking versus change in LGN-V1 coherence. Regression $R^2$: 0.68.

(E) Coupling weights w of the SSM model fits to the data in (B)–(D) (p > 0.05; Wilcoxon signed-rank test).

(F) V1 and LGN Neuropixels recordings during natural movie periods.

(G) As Figure 5E, but during natural movie periods.

(H) As Figure 5F, but during natural movie periods.

(I) As Figure 5G, but during natural movie periods (^∗p < 0.05; ^∗∗p < 0.01; ^∗∗∗p < 0.001; Wilcoxon Mann-Whitney test, comparisons between areas or layers).

(J) Distribution of pupil diameters.

(K) LGN-V1 coherence for gray screen and natural movie periods (n = 7 mice,p < 0.05; Wilcoxon signed-rank test).

(L) LGN-LGN phase locking for gray screen and natural movie (n = 7 mice, p < 0.05; Wilcoxon signed-rank test).

(M) Stimulus-related change in LGN-LGN spike-field locking versus change LGN-V1 coherence. Regression $R^2$: 0.28.

(N) As (E), but now for natural movie and gray screen periods (p > 0.05; Wilcoxon signed-rank test).
