Brain. Historical anatomical artwork of the human brain. This view is from the side, and part of the skin and skull and the outer membranes and blood vessels covering the brain have been removed, showing the folded surface of the cerebrum, the main part of the brain. Another part of the brain, the cerebellum, is the rounded structure (orange) at centre left. The ear hole is seen to the right of the cerebellum, and in the neck at lower left the spine has been dissected in half lengthwise, showing the spinal cord. Artwork from the 19th- century book Atlas of Anatomy, by Bourgery and Jacob. This book, which took over 20 years to complete, was published in France in 8 volumes from 1831 to 1854. It contained 726 colour plates covering both anatomy and surgical techniques.
