Scientists Have Found Secret Tunnels Between The Skull And The Brain
A hidden passage we never knew existed.
-
Did you know you have tiny tunnels in your head? That’s OK, no one else did either until recently! But that’s exactly what a team of medical researchers have just found in mice and humans - tiny channels that connect skull bone marrow to the lining of the brain.
-
The research shows they may provide a direct route for immune cells to rush from the marrow into the brain in the event of damage.
-
Previously, scientists had thought immune cells were transported via the bloodstream from other parts of the body to deal with brain inflammation following a stroke, injury, or brain disorder.
-
This new discovery suggests these cells have had a shortcut all along.
