Fig. 5: Transition probabilities between sleep stages and the simulation of hypnograms.
From: Sleep as a random walk: a super-statistical analysis of EEG data across sleep stages
Transition probabilities (color coded) from one non-interrupted sleep stage to the next (a) and from one 30 s epoch to the next (b). The stage-to-stage probabilities describe a strong propensity for transitions from Wake to N1 and from there to N2. After this, the most likely behavior is an oscillation between N1 and N2, or between N2 and N3. c Example of a simulated hypnogram, where the random walk between sleep stages is modeled as a Markov process, based on the epoch-to-epoch transition probabilities (top right).
