Vasculature of the Brain's Cortex

Caption: The vasculature of the brain's cortex is organized with large arteries and veins on its surface. Arterioles dive into the cortex to feed capillary beds weaving amongst active brain cells. Ascending venules bring blood from the capillary beds to draining veins. During functional stimulation, blood flow increases in the capillary bed (hyperemia) and dilation of feeding arterioles spreads back up the vascular tree to surface arteries.
