The exposure of the lower part of the posterior cerebral circulation enables a direct proximal and distal vascular control, for example, in case of midline aneurysms arising from the VA-PICA junction [ 16].
From this ventral point of view, the exposure of the upper part of the posterior cerebral circulation enables a secure vascular control both proximal and distal, for example, in case of basilar tip aneurysms.

Here, a constitutive transmigration of leukocytes takes place to enable leukocyte circulation between blood and lymphatic organs, in contrast to normal venules, where transmigration only occurs in case of inflammation [ 14, 15].

But what about a BBC that is operating on the web: a global, commercialised space that is minimally regulated, dominated by the economic models of the west coast of the US, large enough for anyone to publish their material on it, and formally organised so as to enable the circulation and sharing of material in unprecedented ways?
