svefnvenjum
Svefnvenjum is a theoretical construct in sleep science used to describe a proposed network of brain regions that coordinate the onset of sleep and the regulation of sleep stages. The term is not widely used in standard sleep textbooks and is primarily encountered in didactic or speculative discussions about sleep architecture.
The concept envisions interactions among brainstem arousal centers, the hypothalamus, thalamus, and cortex, mediated by neurotransmitter
In current research, sleep onset is studied through separate components and networks, including the brainstem arousal
Clinically, insomnia, hypersomnia, and other sleep disorders are addressed by interventions that influence broader sleep-regulation mechanisms
