It is not clear exactly how the system works. However, some research has shown that the movement of blood vessels might help move the waste-clearing fluid where it needs to go. Finding the system in humans is not easy. RegularMRI scansc...

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 fluid called CSF.D. The electrical activity.(A)67. The researchers at Boston University foundA. CSF came into the sleeping brain every 20 secondsB. brains were cleaned when blood came outC. the brains worked more slowly when asleepD. the rhythm of the brain was slower than that of ...
Cerebrospinal fluid -- the clear and watery substance that bathes the brain and spinal cord -- is much more important to brain development than previously realized. Howard Hughes Medical Institute investigator Christopher Walsh, his postdoctoral fellow Maria Lehtinen, former student Mauro Zappaterra, an...
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 ...
I got back in the car and I drove home to sleep it off. Along the way, I stopped and threw my gun into the Royal River. I feel I've been very clear on this point. “不。我渐渐冷静了下来。我走回车里,开车回家睡觉来忘掉这件事。路上,我停了下来,把枪扔到了皇家河里。这一点,我...
In the absence of a true lymphatic system in the brain parenchyma, alternative clearance pathways for excess fluid and waste products have been proposed. Suggested mechanisms for clearance implicate a role for brain interstitial and cerebrospinal fluids. However, the proposed direction of flow, the an...
