Although past studies have shown that extended periods of wakefulness cause changes in gene expression (for review see [ 15 ] ), no causal relationship between changes in gene expression and sleep homeostasis has been identified.
A mathematical algorithm was used to quantify the sleep-wake dependent dynamics of delta power during both baseline and recovery from SD [ 10 ] . In this algorithm, delta power decreases during NREMS and increases during wakefulness according to saturating exponential functions, the time constants of which are estimated by minimizing the square of the differences between empirical (delta power) data and the values produced by the mathematical functions.
, sleep bout duration; [ 12 ] ), and/or sleep intensity observed after an extended period of wakefulness are all taken as evidence that sleep drive is increased during wakefulness and thus that sleep is homeostatically regulated.
Homeostatic and circadian mechanisms interact to determine the duration and quality of sleep and wakefulness [ 3 4 5 ] . Homeostatic regulation of sleep can still be observed in animals that lack circadian rhythms after lesioning of the SCN [ 6 7 8 9 ] , suggesting that circadian rhythms and sleep homeostasis are independent processes.
Homeostatic regulation of sleep can be quantified objectively after a period of enforced wakefulness (i.e.
