Changes in regional bifurcation parameters during sleep relative to wakefulness. Rendering of the regions associated with very large effect sizes (d_Cohen> 0.8) in the comparison of the bifurcation parameters corresponding to sleep (N1, N2, and N3) vs. wakefulness. Red and blue regions indicate d_Cohen> 0.8 for wakefulness < sleep and wakefulness > sleep, respectively. This implies that sleep transitions the dynamics towards a≈0, i.e. dynamics become more susceptible to external perturbations.
