Network structure and dynamics of sleep-wake regulation

Abstract

It is well known that mammals and other animals cycle between periods of sleep and wakefulness. Several recent studies have analyzed the durations of sleep and wake periods (or bouts) in adult mammals and found that wake bouts follow a power law distribution, while the durations of sleep bouts are characterized by an exponential distribution. Motivated by these studies and recent models of sleep-wake regulation, we investigate how the structure of such a neural network might contribute to the observed dynamics. In particular, we consider simple stochastic processes on different random networks and present some preliminary results relating the structure of the network with the distribution of event durations on the network.
