Waves of Fluid Bathe the Sleeping Brain, Perhaps to Clear Waste
During deep sleep, rhythmic pulses of cerebrospinal fluid are coupled with slow waves of electrical activity and fluctuating blood levels in the human brain.

During sleep, waves of fluid surge into the brain and can be visualized with functional MRI. At an earlier timepoint (left), a wave of blood (red) is followed (right) by a pulse of cerebrospinal fluid (blue) into the fourth ventricle.

The facility now known as the Cave Historique des Hospices de
Strasbourg was installed at the Hôpital Civil de Strasbourg in France in
1395 to store wine. Doctors of the Middle Ages used wine to treat
various illnesses, support patients’ well-being, clean wounds, and
sterilize surgical equipment. The wine cellar at the Hôpital Civil was
in use for hundreds of years, until physicians turned away from the
medical use of wine and the barrels began deteriorating from neglect. In
1996, the hospital revived the use of the barrels, and local winemakers
continue to age wine in them—for recreational rather than therapeutic
consumption. WIKIMEDIA, IAN COATES
