Authors: Alexander A. Borbély

Human Neurobiology 1982;1(3):195–204

TL;DR

Original statement of the two-process model: a sleep-homeostatic Process S (rises in wake, decays in sleep) interacting with a circadian Process C sets sleep timing and intensity. Conceptual ancestor of essentially all biomathematical fatigue models (per Mallis et al. 2004).

  • Form factor: software (sleep/schedule input; wrist actigraphy optional)
