Component
SCN-dependent heat loss and sleep response in rats
Context-specific entity; species, compartment and exposure are stated on each claim.
2 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
NMDA-receptor antagonists blocked glycine-associated cutaneous blood-flow responses in the rat experiments, whereas strychnine did not.

## glycine-sleep-nmda-route The tested sleep-related response used a different receptor route from the inhibitory glycine channel. NMDA-receptor antagonists blocked glycine-associated cutaneous blood-flow responses in the rat experiments, whereas strychnine did not. Model: Rat brain injection and antagonist experiments. Limitations: Antagonist evidence supports pathway involvement; does not show all sleep effects use this route. Evidence access: Primary abstract The sleep-promoting and hypothermic effects of glycine are mediated by NMDA receptors in the suprachiasmatic nucleus. · 2015 · https://pubmed.ncbi.nlm.nih.gov/25533534/ · DOI 10.1038/npp.2014.326
Complete structured claim and evidenceGlycine increased cutaneous blood flow and promoted sleep in the rat experiments; SCN ablation abolished the reported sleep-promoting and hypothermic responses.
