Neuroscientists studying Michelangelo's Sistine Chapel ceiling suggest that the artist worked a depiction of the human brainstem into the neck of God in the painting "Separation of Light From Darkness." From CNN:

"He recognized that the brain was an important structure, and I think he included it in the creation of the universe because he recognized that this is one of the most magnificent things that God had created," (Johns Hopkins University neurosurgeon Rafael) Tamargo said…

In the image above, on the left, you can see a comparison between the neck of God in the painting and a real brain stem. On the right, notice the different angles of light on the figure, which was uncommon for Michelangelo…

Tamargo and colleagues are not the first to propose that Michelangelo hid brain anatomy in his paintings. An article in the Journal of the American Medical Association in 1990 by Dr. Frank Lynn Meshberger suggested that the Renaissance master's "Creation of Adam," another fresco from the Sistine Chapel, depicts the human brain.
