Hidden bacterial molecules in the brain reveal new secrets of sleep
New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting it’s a collaborative process between our bodies and microbiomes. The theory links microbes not only to sleep but also to cognition, appetite, and behavior, pointing to a profound evolutionary relationship.
