The Brain's Drainpipes

The human body is an extraordinary thing! It has intrigued scientists and fascinated painters and sculptors for thousand of years. As early as 3100 BC the ancient Nilotic priests were studying human anatomy in their efforts to heal the sick and injured. The Edwin Smith Papyrus is an example.

Today scientists have been talking about parts of the human anatomy that have become more evident through the use of advanced microscopy and imaging techniques.

The discoveries include the 2017 MRI evidence for lymphatic vessels in the human meninge, the membrane that covers the brain. These vessels drain fluids and removes waste from brain tissues.

Early reports of lymphatic vessels in the meninges appeared in the 18th century but were met with skepticism. However, lymphatic vessels in mouse meninges were reported in 2015.
