Hey there! Have you ever heard the saying that you need a brain to get ahead? Well, here’s a story that might make you think twice! It’s about a chicken named Mike who lived without his head. Sounds crazy, right? But it really happened back in 1945!
So, here’s what went down. A farmer in Colorado accidentally cut off Mike’s head with an axe. But instead of dying, Mike kept on living for another 18 months! How is that even possible? Well, when Mike’s head was chopped off, the axe missed some super important parts: the jugular vein and the brain stem. These parts are crucial because they control basic life functions like breathing and heartbeats.
Even though Mike lost most of his brain, the brain stem was still there, and it kept him alive. This part of the brain is connected to the spine and can handle basic tasks like reacting to things and keeping the body running.
Believe it or not, humans can also survive with just a brain stem. There was a boy named Trevor Judge Waltrip who was born with a rare condition called “hydranencephaly.” This meant that instead of having a full brain, his skull was filled with fluid. Trevor lived until he was 12 years old, and like Mike, he could breathe, have a heartbeat, and respond to simple things around him.
Now, losing a head doesn’t mean instant death. There are stories of people who could still move their eyes or blink for a few seconds after decapitation. Scientists think the brain can stay conscious for a few seconds after being separated from the body, but any movements after that are just muscle reactions.
Chickens can also run around for a bit after losing their heads because their muscles can still move without signals from the brain. It’s a bit like a reflex action.
Chickens aren’t the only creatures that can survive without a head. Cockroaches are famous for this too! They have a different kind of circulatory system where blood flows freely in their bodies. This means that when a cockroach loses its head, it doesn’t suffer a big drop in blood pressure like humans or chickens do.
Plus, cockroaches breathe through tiny openings along their bodies called spiracles. This allows them to live for weeks without a head!
So, there you have it! The incredible story of Mike the Headless Chicken and other headless wonders like cockroaches. If you have more science questions, feel free to ask, and keep exploring the amazing world of science!
Imagine you’re a comic book artist! Create a comic strip that tells the story of Mike the Headless Chicken. Use your creativity to illustrate how Mike survived without a head and what his daily life might have been like. Share your comic with the class and explain the science behind Mike’s survival.
Conduct a simple experiment to understand the role of the brain stem. Use a reflex hammer (or gently tap your knee with your hand) to observe your knee-jerk reaction. Discuss how this reflex is controlled by the spinal cord and brain stem, similar to how Mike’s basic functions were maintained.
Research other animals that can survive without a head, like cockroaches. Prepare a short presentation or poster that explains how these animals manage to live without their heads. Highlight the differences in their circulatory and respiratory systems compared to humans.
Participate in a class debate on whether humans could survive with minimal brain function, like the boy with hydranencephaly. Discuss the ethical and scientific implications of such cases and explore the role of the brain stem in human survival.
Write a creative short story from the perspective of Mike the Headless Chicken. Describe his adventures and how he might have felt living without a head. Use scientific facts from the article to make your story both entertaining and educational.
Sure! Here’s a sanitized version of the transcript:

They say you need a brain to get ahead, but I already have a head! Hi everyone, Jules here for DNews! There’s an old urban legend about a farmer in Colorado who cut the head off a chicken with an axe, but instead of bleeding to death, the chicken survived headless and just kept running around. It sounds pretty unbelievable, but it actually happened at least once in 1945. Not only did the chicken survive, it went on to live another 18 months.
So, do chickens not actually need their heads? Well, not most of it. When Mike the chicken had his head removed, the axe missed two very vital parts: the jugular vein and the brain stem. It also missed one of his ears, but that wasn’t particularly important for his survival. While Mike was missing most of his higher brain centers, the lower part, which regulates things like breathing and heart rate, was still mostly intact, along with a blood supply to keep it functioning.
There were some things Mike wouldn’t be able to do, like solve complex problems, but since the brainstem is directly connected to the spine in both chickens and humans, it could react to stimuli and maintain basic bodily functions. In fact, a human can technically survive without most of their brain. In 2001, a boy named Trevor Judge Waltrip was born with a rare condition called “hydranencephaly,” where the skull is filled with sacs of cerebrospinal fluid instead of the brain’s cerebral hemispheres. Despite effectively only having a brain stem, Trevor lived to the age of 12. Just like with Mike, Trevor was able to breathe, maintain a heartbeat, and respond to basic stimuli.
Interestingly, simply not having a head doesn’t mean you’re immediately dead. In historical accounts, there were stories of decapitated individuals being able to move their eyes, open their mouths, and blink for a short time. However, scientists believe that the brain only has a few seconds after being removed from the body before losing consciousness. Any movement after that is likely a muscular reaction.
The same happens in chickens. It’s not uncommon for a headless chicken to run around for a little while after decapitation, as the muscles can continue to contract without brain signals. Humans and chickens are not the only animals that can technically survive without a head. Cockroaches can also endure decapitation due to their unique physiology.
When a human or chicken heart beats, it pumps blood around the body. When decapitated, a significant loss of blood occurs, leading to a drop in blood pressure. However, cockroaches have an open circulatory system, where blood flows freely in body cavities and makes direct contact with internal tissues. This means that when a cockroach is decapitated, the loss of blood pressure is not as critical. Additionally, cockroaches can breathe through openings along their body segments called spiracles, allowing them to survive for weeks without a head.
So, there you have it—a living, breathing headless cockroach! If you have any other general science questions, let us know in the comments, and don’t forget to like and subscribe to DNews for more episodes every day of the week.

Head – The upper part of the body that contains the brain, eyes, ears, nose, and mouth. – The head of a fish contains its brain and sensory organs, which help it navigate underwater.
Survive – To continue to live or exist, especially in difficult conditions. – Many plants and animals have adapted to survive in the harsh conditions of the desert.
Circulatory – Relating to the system that moves blood through the body, including the heart and blood vessels. – The circulatory system is essential for transporting oxygen and nutrients to cells throughout the body.
Cockroach – An insect known for its ability to survive in a variety of environments. – Cockroaches are often studied for their resilience and adaptability in changing environments.
Muscle – Tissue in the body that has the ability to contract and produce movement. – The heart is made of cardiac muscle, which helps pump blood throughout the body.
Reflex – An automatic response to a stimulus that occurs without conscious thought. – The knee-jerk reflex is a common example of how the nervous system responds quickly to stimuli.
Breathing – The process of taking air into and expelling it from the lungs. – Breathing is essential for supplying oxygen to the body and removing carbon dioxide.
