Time series for wake vs. sleep state are shown for three species, comparing the model to experimental data. Human: (A) data from [32], (B) model (, h). Elephant: (C) data from [22], (D) model (, h). Opossum: (E) data from [27], (F) model (, h). Noise is added to the model to make sleep patterns less regular (see Methods for numerical details).
