Web21 feb. 2024 · The researchers found that the production of the myelin-forming cells increased the most during deep, rapid-eye movement (REM) sleep. Melatonin, your body’s sleep hormone, has also been shown to promote myelination and increase myelin production by significantly reducing inflammation in the brain (46). WebThese results are in agreement with earlier observations that, in the optic nerve, myelination proceeds from the brain toward the eye. The present data suggest that a significant amount of myelination in the human optic nerve occurs after a full-term (40-week) gestation, during a period of rapid postnatal visual development.
