At a loose end I found myself watching a schlocky gore-fest of a horror film called Re-Animator. It features a goofball scientist who capitulates to his unhealthy obsession with reviving the dead by injecting them with what looks like a radioactive magic serum. Of course this being a comedy-horror, his hapless subjects aren't returned to the land of the living in prime mental or physical condition; they are transformed into zombiefied, slathering imbeciles. They develop super-human strength and plunge headlong into murderous rampages - some even do so without their heads!
Aside from wishing I could have the 90 minutes I invested watching this trashy nonsense refunded, the film got me wondering if the events portrayed really are as far-fetched as they first appear. No, bear with me. We know doctors are able to defibrillate patients back to life shortly after their heart has stopped, so the real brain-teasers are:-
What is the shelf life of a human or animal corpse? If they're brought back after, say, 10 minutes, will they continue to function normally? What is the cutoff point?
Can internal organs be substituted for man-made contraptions in order to keep an organism alive? If so, which ones are viable?
Is it possible for a decapitated brain to retain consciousness? How long for, and under what conditions?
The following research aims to answer some of these questions:-
As far back as 1940 the Russians were killing and resurrecting dogs in the name of science. This video demonstrates the artificial sustenance of a heart and lung when isolated from the body, the mechanical resuscitation of a dog whose blood has been drained to bring about the cessation of heart, lung and brain activity, and the reactions to various stimuli of a dog's dismembered head! The ill-fated canines weren't the only sick puppies in this scenario! As a dog lover it turns my stomach just thinking about it. A Wikipedia article on the experiments can be found here.
More recently a US scientist claims to have yanked a three-hour-dead dog back from the other side. The procedure entailed draining the dog's blood thereby forcing the heart to shut down. A cold saline solution was then pumped into its blood vessels effectively lowering its metabolism to bring about a state of 'suspended animation'. After three hours had elapsed blood was pumped back into the dog and its heart was defibrillated.
Again in the US, a similar method has been used to save pigs from - artificially induced - certain death. The doctors are now seeking approval to trial the technique using human car crash and gunshot victims. Let's hope if they get the go-ahead they'll let their wounds occur naturally.
The freaky case of Mike the Headless Chicken goes some way towards explaining how the body of a bird adapts to life without a head.
For some truly disturbing human examples refer to this article.
You won't be laughing when your pickled undead head is languishing in a jar on the mantelpiece... [Dr Evil little finger to the corner of the mouth thing] or will you?
