Ultrafast venous and sagittal sinus constrictions in the brain driven by abdominal pressure

Nearly all the blood supplying the cortex exits via the bridging veins (BVs) that drain into the superior sagittal sinus (SSS), making these vessels key chokepoints for cerebral blood flow. Using optical imaging in head-fixed mice, we found that the SSS, BVs, and some other pial...
