Summary:
We study a physiologically-motivated multineuron model of sleep-wake cycle, taking into account the circadian rhythm and the homeostatic regulating role of orexins. Heterogeneity is introduced in the system by diversifying different parameters and its effect on the wake-sleep cycle is investigated. It is shown that in all the cases considered the model exhibits a strong dependence on diversity, either in the form of a diversity-induced resonance or through more complex types of responses.
