I had written before about the breakthrough studies of mice that showed lymphatic flushing of brain tissue while they slept. Now this phenomenon has been confirmed in humans. During human sleep, ...

There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain’s bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts ...

Scientists have long been puzzled over how the brain clears away its own waste. Unlike the rest of the body, which relies on the lymphatic system to carry waste from cells into circulation, the brain ...

Cerebrospinal fluid is the liquid around your brain and spinal cord. If a doctor thinks you have an illness that affects your nervous system, they might take a sample for testing. The fluid is made by ...

The brain has a waste-disposal system that clears away junk proteins that contribute to the development of dementia and Alzheimer's disease, a new study finds. Advanced imaging scans have revealed a ...

Scientists have disproved a decades-old orthodoxy: cerebrospinal fluid does not leave the cranial cavity via blood vessels, but instead through the lymphatic system. This finding has far-reaching ...

Hydrocephalus, commonly known as fluid or water on the brain, can occur in the womb or be caused by hemorrhage, tumors, trauma or infection. The “water” in this case is an excess of cerebrospinal ...

To rid itself of extracellular proteins, the brain relies on water transport by cells called astrocytes and on the flow of cerebrospinal fluid. This fluid was thought mainly to provide mechanical and ...
