Baroque Blood Vessels
A scanning electron microscope (SEM) image zooms in on the baroque branching structures that send blood to the human brain’s cortex. The vessels are organized such that the large blood vessels surround the surface of the brain (top of image), sending thin, dense projections down into the depths of the cortex (bottom of image).
