- MRI captures directional fluid movement
Researchers found that spontaneous infraslow hemodynamic oscillations during sleep coordinate spatially structured, directional CSF flow in both ventricular and subarachnoid compartments.
- Field
- the brain and neuroscience
- What they did
- Researchers used MRI to discover that spontaneous hemodynamic oscillations during sleep synchronize the direction of cerebrospinal fluid flow in the subarachnoid space and ventricles.
- Why it matters
- This helps understand how the brain clears metabolic waste during sleep, as cerebrospinal fluid flow is considered a key mechanism for this cleanup.
