Can A Chicken Really Live Without A Head?


They say you need a brain to get ahead, but
I already have a head! Hey brain dead chickens, Jules here for Dnews! There’s an old urban legend that a farmer
in Colorado cut the head off a chicken with an axe, but instead of bleeding to death and
being ground into chicken nuggets, the chicken survived, headless, and just kept running
around. It sounds pretty crazy, but it’s just crazy
enough to true, and it actually did happen at least once, in 1945. Not only did the chicken survive, it went
on to live another, very famous, 18 months. So, do chickens not actually need their heads? Well, frankly, not most of it. When Mike the chicken had his head lopped
off, 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 to his survival. So while Mike was missing pretty much every
part of his higher brain centers; the lower part, which regulates things like breathing
and heart rate, was still mostly intact. And with a blood supply to keep it going. There were some things Mike wouldn’t be
able to do, like math, but since the brain stem attached directly to the spine, in both
chickens and humans, it could react to stimuli and keep the body in homeostasis, and well…
not dead. 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”. This is where the skull is filled with sacs
of cerebrospinal fluid instead of the brain’s cerebral hemispheres, which is the vast majority
of what we think of as “brain”. But 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. And on an aside, simply not having a head
doesn’t mean you’re immediately dead. Back when people got their heads cut off by
guillotines, when France was cool, there were anecdotal stories about body-less heads able
to move their eyes, open their mouths as if to speak, and blink for up to 30 seconds. But today, scientists think that the brain
really only has a few seconds after being removed from the body, and thus a source blood
and oxygen, before falling into a coma and dying. Any action after those few seconds is most
likely a muscular reaction. The same happens in chickens. It’s not uncommon for a headless chicken,
even one missing its brainstem, to run around for a little while after decapitation. The headless chicken’s muscles can continue
to contract for a short while without a brain telling them to do so. And humans and chickens are not the only animals
technically able to survive without a head. Cockroaches can also cheat death, because
they’re designed differently from us. When a human or chicken heart beats, it pumps
blood around the body to give it the energy and oxygen it needs. And one of the many things that happens when
you’re decapitated is you lose a lot of blood, and your blood pressure drops, and your heart
can’t keep up. But cockroaches don’t rely on blood pressure. Cockroaches and many other invertebrates have
something called an open circulatory system, where instead of going through blood vessels,
the blood floats just around in the body cavities and makes direct contact with the internal
tissues and organs. That means that when a cockroach is decapitated,
the threat of the loss of blood pressure is not that big of a deal. Moreover, the roach can keep breathing with
the brain entirely. Roach breath comes in through holes along
the body segment called called spiracles, that send air to the cells that need it. And because they don’t need to eat as often
as humans, roaches they can survive weeks without a head. This gives you a living, breathing, headless
cockroach. Ok, I think my nightmares are set for the

    Scientists are so stupid guessing. Running around isn't a muscular response but takes coordination the chicken didn't have at birth but learned. If it were a muscular response it wouldn't run around but to have the complex coordinated motion of running around shows scientist guess wrong about where consciousness exists in creatures namely chickens.
