Tiny channels discovered inside the human skull could be vital for the brain

Leave a Comment / Health / By

A shortcut between the skull and the brain could be a possible way for the human immune system to bypass the blood-brain barrier. Researchers have recently discovered a series of tiny channels in the skulls of mice and humans, and in mice at least, these small channels represent an unexpected source of cerebral immunity. Previously, …
