The majority of cells in the human brain are not nerve cells but star-shaped glia cells, the so called “astroglia”.

人脑大部分细并非神经细，而是星状胶质细。

The permeability of blood-brain barrier (BBB) was detected by Evans Blue (EB) leakage method, and the ultrastruncture of BBB, which contained astroglia, was observed under electron microscopy.
