Greater hypoxic burden predicts weaker coordination between brain pulsation and CSF flow on 7T MRI independent of non-hypoxic arousals: Implications for glymphatic activity

This study finds that greater hypoxic burden in OSA is linked to weaker coordination between brain pulsation and CSF flow, suggesting impaired glymphatic activity.

CILIATED CELL DOMAINS WITH LOCALLY COORDINATED CILIARY MOTION GENERATE A MOSAIC OF MICROFLOWS IN THE BRAIN'S LATERAL VENTRICLES

The paper investigates flow patterns in the brain's lateral ventricles, revealing local microflows generated by clustered ciliated cells with varying polarity alignment.

Cerebral Venous Blood Flow Regulates Brain Fluid Clearance via Dural Lymphatics

This study shows that dural venous stenoses impair lymphatic drainage and brain fluid clearance, and that restoring venous flow can improve clearance in a mouse model.

VEGF-C promotes brain-derived fluid drainage, confers neuroprotection, and improves stroke outcomes

This study shows that VEGF-C overexpression enhances brain fluid drainage, provides neuroprotection, and improves stroke outcomes in mice.

Choroid plexus tissue perfusion and secretory function in rats measured by non-invasive MRI reveal significant effects of anesthesia

This study uses non-invasive MRI to measure choroid plexus perfusion and secretory function in rats, finding that anesthesia affects perfusion but not secretory function.

Development of an MRI Compatible Nasal Drug Delivery Method: Probing Nicotine Addiction Dynamics

This paper develops an MRI-compatible nasal delivery system for nicotine to study addiction dynamics and confirms its ability to elicit craving cycles and activate addiction-related brain circuits.

Cerebrospinal Fluid and Interstitial Fluid Motion via the Glymphatic Pathway Modelled by Optimal Mass Transport

This study models glymphatic fluid flow in a live rat brain using optimal mass transport and diffusion equations to predict tracer concentrations.
