Mammalian Sleep Dynamics: How Diverse Features Arise from a Common Physiological Framework
Figure 4
Positive correlation between homeostatic time constant and body mass.
Log-log plot of homeostatic time constant (ranges from regions in Fig. 2) vs. body mass for 17 species. Linear fits are shown for non-primates (solid, ), corresponding to a power law with exponent 0.29±0.10 (Mean±S.D. calculated using bootstrapping), and for primates (dashed,
) with exponent 0.01±0.26. A linear fit to all species (
) yields an exponent of 0.28±0.12.
