Amyloid starts in your brain, and some drifts down your spine in your cerebrospinal fluid. From there a little tiny bit leaks out into your blood.

淀粉样蛋白始于大脑，一些淀粉样蛋白沿着脊髓向下流，进入脑脊液中，流经此处，少量淀粉样蛋白会渗漏到血液中。

The third ventricle makes a bit more cerebrospinal fluid and then sends all of it to the fourth ventricle via the cerebral aqueduct.

第三脑室也产生一些脑脊液，然后把全部的脑脊液通过大脑（脑室系统）导水管排入第四脑室。

Fluid from the brain, called cerebrospinal fluid, travels through channels surrounding blood vessels to carry waste out of the brain.

Those who performed the worst also tested positive for biomarkers of Alzheimer's in their cerebrospinal fluid.

那些表现最差的人的脑脊液中阿尔茨海默病的生物标志物检测也呈阳性。

For example, as pinealomas, medulloblastomas, and ependymomas enlarge - the mass of the tumor can compress nearby ventricles blocking the flow of cerebrospinal fluid which causes swelling, called hydrocephalus.

例如，随着松果体瘤、髓母细胞瘤室管膜瘤的增大，巨大的肿瘤可以压迫一旁的脑室，阻断脑脊液的流动，从而引起组织肿胀，称为脑水肿。

When these findings present a lumbar puncture should be performed for cerebrospinal fluid analysis to confirm the diagnosis.

当存在这些症状时，需要做腰穿收集脑脊液来确定诊断。

The blood vessels are labeled in red and the cerebrospinal fluid that's surrounding the brain in green.

The video on the left shows how much of the cerebrospinal fluid is moving through the brain of a mouse while its awake, barely anything.

左侧的视频展示的是一只醒着的老鼠的大脑有多少脑脊液流动，几乎没有。

Finally, sometimes the bacteria can even migrate from the bloodstream, and use its toxins to break through the endothelial cells that make up the blood-brain barrier to get into the cerebrospinal fluids or CSF, causing meningitis.

最后，细菌有时可以通过血液循坏进入脑：其释放毒素杀伤血管内皮细胞，破坏其构成的血脑屏障，从而进入脑脊液，导致脑膜炎。

Also, in the cerebrospinal fluid there might be high levels of antibodies, which indicates an autoimmune process.

还有脑脊液中可有抗体水平增高，暗示有自身免疫活动。

So this makes it possible for cerebrospinal fluid to also flow through the central canal of the spine.

因此，脑脊液也可流入脊髓中央管。
