I must say that after reading your piece below on squash I was more interested in the video and began to wonder why is it chickens run around after having their heads cut off? So I set off and searched the world wide web (or rather google) and below is what I found out:Chickens seldom run after their heads are cut off. When they do, it is because the head was cut too close, and part of the brain stem or upper spinal cord, containing the relevant circuits, are still there. The reason chickens run around with their heads cut off is because of a panic reaction. The last message the brain sends to the nerves is to escape and flee and panic all rolled into one. So the nerves follow the last message the brain sent them before being cut off. Then the decapitated chicken runs madly around until its heart stops.
Pretty amazing how the chickens body follows that last command and the nerves remain active, causing the muscles to work by doing what they were last told.
Even more amazing is this true story about a headless chicken named Mike that lived for 18 months after being decapitated! Mike's original purpose what to be dinner for the chicken owner's mother in law!
