The blood-brain barrier prevents xenobiotics from entering the central nervous system. Growing evidence indicates that neurotoxins, such as tributyltin, manganese and nanoparticles, may disrupt the ...

One key role of sleep involves cerebrospinal fluid, which surrounds and protects the brain. During sleep, CSF helps remove waste that accumulates during waking hours. In a 2019 study, Lewis and her ...

The cerebrospinal fluid from young mice is awash with factors that keep the brain sharp. Now, scientists led by Tony Wyss-Coray at Stanford University in Palo Alto, California, report that when ...

Your brain ventricles are four fluid-filled chambers that produce cerebrospinal fluid. This fluid helps nourish your brain and protect it from injury. It would be easy to argue that your brain is the ...

Problems with the brain's waste clearance system could underlie many cases of dementia and help explain why poor sleep patterns and cardiovascular risk factors such as high blood pressure increase the ...

Sleep deprivation triggers CSF movements during wakefulness, briefly pushing the brain into a sleep-like state that disrupts ...

Abnormal clumps of proteins like α-synuclein, amyloid beta and tau are associated with neurodegenerative conditions like ...

Scientists at the Institute for Basic Science (IBS) have uncovered a non-invasive method to boost the brain’s natural waste drainage system—a discovery that they suggest could open new avenues for ...

New research shows sleep deprivation can push the awake brain into a sleep-like state, disrupting attention and brain fluid ...
