Different brain states are mirrored by different properties of the underlying functional networks.

(A) Distribution of the correlation coefficients and corresponding average FC matrices obtained from deep and light intervals. The two distributions were statistically different (*** indicates p < 0.001, see Results). Dark- and light-blue triangles indicate the means of the deep and light distributions, respectively.

(B) Average matrix of the robust coupled nodes (RCNs; see Materials and methods) obtained from light anesthesia. The color-code quantifies the average correlation coefficient of those area pairs that were classified as RCNs. Area pairs that were not classified as RCNs are highlighted in light gray.

(C) Community structure of the light RCNs, where nodes of the same colors indicate areas belonging to the same community (see Materials and methods). No community were detected in the deep anesthesia interval.

In panels B and C, nodes that were selected as representative of “coupled” and “uncoupled” area pairs and used for further analysis are highlighted in red and gray, respectively.
