In 1970, after a long series of preliminary experiments, White performed a transplant of one monkey head onto the body of another monkey. Because the surgery included severing the spine at the neck, the subjects were paralyzed from the neck down. After the surgery, because the cranial nerves within the brain were still intact and nourished by the circulatory system from the new body, the monkey could still hear, smell, taste, eat and follow objects with its eyes.
