Dynamics of sleep-wake regulation
Cecilia Diniz Behn

Waking and sleep states are regulated by the coordinated activity of
neuronal populations in the brainstem and hypothalamus whose synaptic
interactions define a sleep-wake regulatory network. Mathematical
models of this network contain mechanisms operating on multiple time
scales. By exploiting the naturally-arising slow time scale of the
homeostatic sleep drive, techniques such as fast-slow analysis may be
used to analyze mechanisms of transition in the deterministic system.
Alternatively, by focusing on stochastic properties of this model
network, the generative mechanisms associated with the fine architecture
of sleep-wake behavior may be investigated. |
