Sleep and wakefulness are promoted not by a single neural pathway but via wake or sleep-promoting nodes distributed across layers of the brain.We equate each layer with a brain region in proposing a layered subsumption model for arousal based on a computational architecture.Beyond the brainstem the layers include the diencephalon (hypothalamus, tha
