Your brain is 10% neurons, and 90% glial cells.

脑由 10% 的神经元和 90% 的神经胶质细胞构成。

They arise from supportive glial cells as well as neurons.

其源于神经胶质细胞或神经元。

Among the fibers is the structural protein glial fibrillary acidic protein that is typically found in astrocytes.

这中有结构状蛋白——胶质酸性蛋白，这蛋白通常存在于星形细胞中。

But more than that the supportive cells called glial cells are now cleaning up the toxins that the neurons produce.

是除此之外，叫作神经胶质细胞的支持细胞，会在你睡觉时清除神经元产生的毒素。

The theory is that if you really tax your brain, the neurofibers will become thicker and the glial cells more lustrous.

理论上来说如果你真的充分利用了脑那你的神经会更加粗壮神经胶质细胞会更有光泽。

Until recently, we thought the glial cells surrounding neurons were just support structures, but now we know they have a huge role in influencing nociception.

直到最近，我们还认为神经元周围的胶质细胞只是支持结构，现在我们知道它们在影响伤害性方面有着巨的作用。

Ammonia appears to mainly target astrocytes, a type of glial cell in the brain, and although the mechanisms aren’t fully understood, ammonia seems to cause astrocyte swelling and oxidative damage.

氨主要出现在星形胶质细胞中，它是脑内的一种神经胶质细胞，虽然具体的机制我们仍然不清楚，不过氨似乎能导致星形胶质细胞肿和氧化损伤。

There are different types of neurons that take care of different functions, but in general, your neurons enable you to process and transmit information, while your glial cells surround your neurons, providing them with support and insulation.

不同种类的神经元有不同功能，总的来说，神经元可以处理和传递信息，神经胶质细胞包围着神经元，为它们提供支持并起到绝缘作用。
