Johns Hopkins researchers have discovered an anatomically correct bottom up view of a brainstem in the part of the Sistine Chapel painting called the Separation of Light From Darkness. It is in god's neck in the painting. This would make the 'Light' a brain and associate it with science.
It seems that Michelangelo did this intentionally in that god's neck in the painting contains abnormalities that he was too talented and too knowledgeable to have painted hap hazardly:
Although the vast majority of subjects in this painting are considered anatomically correct, art historians and scholars have long debated the meaning of some anatomical peculiarities seen on God's neck in the part of the painting known as Separation of Light From Darkness. In this image, the neck appears lumpy, and God's beard awkwardly curls upward around his jaw.
"Michelangelo definitely knew how to depict necks—he knew anatomy so well," says Rafael Tamargo, M.D., a professor in the Department of Neurosurgery at the Johns Hopkins University School of Medicine. "That's why it was such a mystery why this particular neck looked so odd."
Moreover, hidden in the same picture of god the researchers found an anatomically correct spinal chord that was properly proportioned and located:
The structure has the right placement, shape, and size to be a spinal cord, say the researchers, suggesting another piece of hidden anatomy in the artwork.
This is not the first empirical suggestion that Michelangelo associated god with the brain and science in the painting of the Sistine Chapel. In 1990 Dr. Frank Lynn Meshberger, an obstetrician in India, published a paper contending that the shroud surrounding the the image known as the Creation of Adam strongly resembled an anatomically correct brain.
The Johns Hopkins researchers represent what might be the best medical school in the world. Per Wikipedia (Ranking and Reputation):
Hopkins has consistently been the nation's number one medical school in the amount of competitive research grants awarded by the National Institutes of Health. Its major teaching hospital, The Johns Hopkins Hospital, has been ranked as the best hospital in the United States every year since 1992 by U.S. News and World Report Askmen.com lists an M.D. from the Johns Hopkins School of Medicine as one of the five most prestigious degrees in the world.
The Johns Hopkins researchers are continuing their investigation.
