The results are as follows.
1. Anatomically the perivascular space streches from the subarachinoid space along vessels of the brain to the surrounding of small vessels, the first region by Alexander and Putnam. It seems that there is a septum, which permits only functionally the intercommunication of the cerebrospinal fluid, between the surrounding of small vessels and the pericapillary.
2. The perivascular space extends forward from the pia trichter along vessels, forming the walls of the space with each single layer of the arachinoid and the pia mater, the former the inner wall, the latter the outer wall, and on to small vessels, the first region.
3. The pericapillary leaves an interval between the wall of capillaries and the glial membrane. Anatomically the pericapillary space communicates with the surrounding of glia cells, and it is natural that the passage of the cerebrospinal fluid can be expected.
4. The network of lattice fibers is found both in the perivascular space and pericapillary one.
