The team also discovered that, in mice given the sleep aid zolpidem, the slow fluctuations in noradrenaline vanished, and the flow of CSF into the brain was around 30% lower than it was in mice ...

Research shows that during deep, non-rapid eye movement (REM) sleep, the brain’s interstitial spaces expand, allowing CSF to flow more freely and flush out accumulated waste. Conversely, poor or ...

For years, scientists thought the brain lacked a lymphatic system, raising questions about how fluid, macromolecules, and immune cells escape the organ. In 2015, two studies in mice provided evidence ...
