Human brain in the midline on top of the brain. Blood from here joins with blood from the straight sinus at the confluence of sinuses. Blood from here drains into the left and right transverse sinuses. These then drain into the sigmoid sinuses, which receive blood from the cavernous sinus and superior and inferior petrosal sinuses. The sigmoid drains into the large internal jugular veins. The larger arteries throughout the brain supply blood to smaller capillaries. These smallest of blood vessels in the brain, are lined with cells joined by tight junctions and so fluids do not seep in or leak out
The Tell-Tale Brain The Tell-Tale Brain The Tell-Tale Brain: A Neuroscientist's Quest for What Makes Us Human is a 2010 nonfiction book by V. S.

Ramachandran discusses seven main concepts which define the human aspect of self and how each may be disrupted by a
