From: Reversed and increased functional connectivity in non-REM sleep suggests an altered rather than reduced state of consciousness relative to wake

Figure 5

Cartoon of possible polynomial fits for functional connectivity (FC) data across wakefulness and sleep. (A) Null hypothesis (H0); first-order polynomial, horizontal line fit. (B) Alternative hypothesis 1 (H1); first-order polynomial, non-horizontal line fit. (C) Alternative hypothesis 2 (H2); second-order polynomial, quadratic line fit. (D) Alternative hypothesis 3 (H3); third-order polynomial, cubic line fit. REM rapid eye movement, NREM2 non-REM stage 2, SWS slow wave sleep.
