Table 1. Dependence of regressands on channel set location and distance among channels.

	Location			Distance
Regressand	βb	χ2(1)c	p	βb	χ2(1)c	p
Φ Within	-9.16	44.30	< .001	-2.10	52.11	< .001
Φ Across	-5.76	16.77	< .001	-0.47	2.56	.110
IIS Within	-7.89	32.71	< .001	-2.09	51.05	< .001
IIS Across	-9.06	42.03	< .001	-0.90	9.31	.002

Regressands were the classification accuracies reported in Fig 5C–5F. Φ Within: within-fly classification accuracy using Φ, system-level integrated information. Φ Across: across-fly classification accuracy using Φ. IIS Within: within-fly classification accuracy using IIS, integrated information structure. IIS Across: across-fly classification accuracy using IIS. Location: average location of channels in a channel channel set. Distance: sum of pairwise distances between channels within a channel set.

b β from regressing z-scored classification accuracies; values are ×10⁻²

c The degree of freedom for all likelihood ratio tests was 1 (see Methods).
