🐭🧠 #PrecapillarySphincters (PS) at the #arteriole–#capillary junction rapidly dilate ~30% in seconds during #SensoryStimulation—regulating #capillary #BloodFlow dynamically. Here we investigated whether they protect downstream microvessels during abrupt #BloodPressure surges 🧪🧵

Your brain functions not only as a thinking organ but also as a miniature water factory. We here calculate how much water neuronal mitochondria produce by glucose oxidation: 300-400 ml. Of that amount, 100 ml go into brain's interstitial fluid. fluidsbarrierscns.biomedcentral.com/articles/10....

Once again, someone else says it: "Aβ accumulation affecting brain vessel function could be a very early pathology leading to neurodegenerative disease." doi.org/10.1186/s131... #cerebrovascular
