The article discusses a medical condition wherein one has an abnormal fluid increase in the brain. Such condition is known as normal-pressure hydorcephalus (NPH). NPH can happen to anybody although it is reportedly more common am...
In searching for the drainage route of the interstitial fluid (ISF) in the deep brain, we discovered a regionalized ISF drainage system as well as a new function of myelin in regulating the drainage. The traced ISF from the caudate nucleus drained to the ipsilateral cortex along myelin fiber ...
根据第二段中的“ With little gravity in space, fluids build up in an astronaut's head. Extra fluid collects in four chambers in the brain, called ventricles. "可知, 在太空中几乎没有重力的情况下,宇航员的头 部会积聚液体,多余的液体会聚集在脑室中。 由此可知,失重的环境导致液体聚集在宇航员 ...
The glymphatic system exhibits diurnal variation First, we tested the hypothesis that there was a day/night difference in influx of CSF tracer along the perivascular spaces around the middle cerebral artery (MCA) of the brain. Mice were anesthetized with ketamine/xylazine (KX) at mid-day or mid...
Flow of cerebrospinal fluid (CSF) through perivascular spaces (PVSs) in the brain is important for clearance of metabolic waste. Arterial pulsations are thought to drive flow, but this has never been quantitatively shown. We used particle tracking to quantify CSF flow velocities in PVSs of live ...

Amyloid-β and Tau Dynamics in Human Brain Interstitial Fluid in Patients with Suspected Normal Pressure Hydrocephalus. Amyloid-β (Aβ1 - 42), total tau (T-tau), and phosphorylated tau (P-tau181) in the cerebrospinal fluid (CSF) are the most promising biomarkers of Alzheime... Sanna-Kaisa...
Hydrocephalus is a common disorder caused by the buildup of cerebrospinal fluid (CSF) in the brain. Treatment typically involves the surgical implantation of a pressure-regulated silicone tube assembly, known as a shunt. Unfortunately, shunts have extremely high failure rates and diagnosing shunt malf...
