Thanks, that's interesting. This shows the shallowness of my understanding: > It has been known for centuries that the dura mater may harbor lymphatic vessels but the role of meningeal lymphatic vessels (MLVs) regained renewed interest since 2015, when functional MLVs were first reported. Life is incredibly complex, ours most of all. But finding new ligaments is really crazy.
