Elizabeth Klerman – Review of mathematical models of circadian rhythms

I will review current mathematical models of circadian rhythms, their inputs, outputs, and structure and then areas in which new work is needed – especially adjustment of models to predict inter-individual differences rather than describe group averages.

Cecilia Diniz Behn - Modeling interactions between circadian rhythms and sleep

In mathematical models of sleep, representations of circadian rhythmicity determine sleep timing under both entrained and perturbed conditions. I will review the role of circadian rhythms in sleep/wake models and the ways in which the complexity of these representations crucially affects sleep/wake dynamics.
