On March 14th, 1970, a groundbreaking experiment took place in an operating room. Neurosurgeon Robert White and his team embarked on an ambitious mission involving two small monkeys. White aimed to attach the head of one monkey to the body of another, a procedure he referred to as a whole-body transplant. His ultimate dream was to one day perform this surgery on humans.
The concept of a body transplant raises numerous ethical, biological, and philosophical questions about life and the boundaries of science. However, the primary question is whether such a procedure is even medically feasible. White’s surgery faced significant technical challenges. One major issue was paralysis, as no doctor then—or even now—could reconnect a severed spinal cord. Despite this, White believed that the surgery could be life-saving for patients with spinal cord injuries or progressive diseases like ALS, which often lead to multi-organ failure and paralysis. He hoped that a body transplant could save their lives by replacing all their organs simultaneously.
Paralysis was not the only hurdle. Brain cells need a constant supply of oxygenated blood to survive, and the transplant surgery would likely disrupt the brain’s oxygen flow for hours. White had an innovative idea: cooling the brain to slow its metabolism, thereby reducing its oxygen needs. He experimented with dogs and monkeys, perfecting a brain-cooling technique that selectively chilled and stopped blood flow to the brain while keeping the rest of the body warm and circulating blood. In 1964, White successfully cooled the brain of a human patient with a life-threatening brain tumor to a state of “suspended animation” at 11°C, allowing the surgical team to operate for over an hour without causing damage.
While brain cooling revolutionized neurosurgery and brought White closer to his goal of a body transplant, it also raised serious ethical concerns. Questions emerged about what conditions would justify such an experimental surgery, which could result in severe pain and neurological damage, and how many animals would need to be sacrificed to prove its feasibility. At the time, bioethics was still an emerging field, and many critics, including those within the scientific community, recognized the ethical implications of White’s research.
Despite opposition, White continued to gain approval from agencies like the NIH, and by 1970, he was ready to attempt a monkey body transplant. First, Monkey A was fitted with temporary blood vessels—plastic tubes that connected the head to the body. The team connected Body B to Head A and waited for the subject to wake from anesthesia. The monkey did awaken—alive, paralyzed, and in distress. According to the team, the monkey could see, smell, hear, and even attempted to bite one of the doctors’ fingers. White felt this demonstrated that the operation could work, as the brain appeared to survive the head transplant and, with high doses of drugs, could live without immune rejection.
This experiment raised further questions: had White performed a body transplant on Monkey A, or was it a head transplant on Monkey B? The surgery sparked discussions about the mind-body connection that have been debated for centuries. While modern neuroscience supports the brain’s central role in consciousness, discoveries about gut neurons and the microbiome suggest that the relationship may be more complex. Does part of the “self” reside outside of the mind? The body and brain are interconnected, so what is lost by separating the two?
As a neurosurgeon, White performed over 10,000 brain operations before retiring in 1998, but he never achieved the human head transplant he envisioned. Since then, several scientists have expressed interest in continuing his work, reigniting unresolved debates. Even if a doctor could successfully connect a patient’s head to a donor’s body, questions remain about identity and the value of extending life at any cost.

Research a neurosurgical innovation that has emerged since Robert White’s experiments. Prepare a presentation that explains the technology, its applications, and how it addresses some of the challenges faced in White’s time. Highlight any ethical considerations associated with the innovation.
Analyze a case study of a real or hypothetical patient who might benefit from a body transplant. Discuss the medical, ethical, and psychological factors that would need to be considered before proceeding with such a surgery. Present your findings in a written report.
Participate in a group discussion exploring the philosophical questions raised by the concept of body transplants. Consider the implications for personal identity and consciousness. Reflect on how modern neuroscience and discoveries about the microbiome contribute to this debate.
Work in teams to simulate the technical challenges faced during a body transplant surgery. Use models or digital tools to demonstrate how you would address issues like spinal cord reconnection and brain oxygenation. Present your solutions and discuss their feasibility with the class.
On March 14th, 1970, Robert White and his team brought two small monkeys into an operating room. The neurosurgeon was on the verge of an ambitious experiment, which was both unusual and groundbreaking. White’s objective was to connect the head of one monkey to the body of another, a procedure he considered a whole-body transplant. His ultimate goal was to one day perform this surgery on humans.
While the idea of a body transplant raises ethical, biological, and philosophical questions about the nature of life and the limits of science, the first question is whether it is even medically possible. White’s surgery faced several technical challenges. For one, it was expected to result in paralysis, as no doctor at that time—or even now—could reconnect a severed spinal cord. However, White believed that the surgery could be life-saving for patients with spinal cord injuries or progressive mobility diseases like ALS, who often face multi-organ failures and paralysis. He hoped that a body transplant could save their lives by replacing all of their organs at once.
Paralysis was not the only challenge. Brain cells require a constant supply of oxygenated blood to survive, and the transplant surgery would likely interrupt the brain’s oxygen flow for hours. White had an idea: when the brain is cooled, its metabolism slows down, reducing its oxygen needs. He experimented on dogs and monkeys, optimizing a brain-cooling technique that selectively chilled and halted blood flow to the brain while keeping the rest of the body warm and circulating blood. In 1964, White successfully cooled the brain of a human patient with a life-threatening brain tumor into “suspended animation” at 11°C, allowing the surgical team to operate for over an hour without causing damage.
While brain cooling revolutionized neurosurgery and brought White closer to his body transplant goal, it also raised serious ethical concerns. Questions arose about what conditions would justify such an experimental surgery, which could result in debilitating pain and neurological damage, and how many animals would need to be sacrificed to prove it was possible. At the time, bioethics was still an emerging field, and many critics, including those within the scientific community, recognized the ethical implications of White’s research.
Despite the opposition, White continued to gain approval from agencies like the NIH, and by 1970, he was ready to attempt a monkey body transplant. First, Monkey A was fitted with temporary blood vessels—coils of plastic tubes that connected the head to the body. The team connected Body B to Head A and then waited for the subject to wake from anesthesia. The monkey did awaken—alive, paralyzed, and in distress. According to the team, the monkey could see, smell, hear, and even attempted to bite one of the doctors’ fingers.
