Remember, when you look at the brain, it is always covered with blood vessels? So they are not on the surface of the brain, they are, as it were, enclosed in the pia mater. Here is a complete overview of the example of the head, it seems, a pig. On the left you see the skin (pink), then two layers of the scalp, then the skull, then the dura mater, the arachnoid, and to the right the brain, covered only with a soft membrane. As soon as we remove all unnecessary, we remain tete-a-tet with this stupid boy. This strange-looking thing is one of the most complex known objects in the universe - a kilogram, as neuroscientist Tim Hanson says, "one of the most informational dense, structural and self-organized substances among all known." All this works with just 20 watts of energy (a computer of equivalent power eats 24,000,000 watts).
