CSF normally flows back and forth through the aqueduct during the cardiac cycle. During systole, the brain and intracranial vasculature expand and compress the lateral and third ventricles, forcing CSF craniocaudad. During diastole, they contract and flow through the aqueduct reverses. Hyperdynamic CSF flow through the aqueduct is ...

WebOct 31, 2024 · Then, a watery liquid called cerebrospinal fluid (CSF) will flow in, washing through your brain in rhythmic, pulsing waves. The study, published on October 31 in Science, is the first to illustrate that the brain’s CSF pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow.
WebSep 25, 2024 · Intracranial pressure: A steady flow of CSF keeps the pressure around your brain stable. Too much CSF, possibly due to a traumatic brain injury or brain tumor, raises intracranial pressure.
