Does the head/brian still function on decapitation?
This has been the subject of much speculation for hundreds of years. Although it is likely that the brain of a severed head might continue to show activity for a few seconds, it is unlikely that the victim will be ‘seeing’ in any significant way. The trauma of decapitation and the sudden drop in blood pressure would cause almost instant unconsciousness. Severed heads do show some involuntary twitching and this has fuelled much speculation on the subject. There are many documented ‘experiments’ where condemned prisoners have been asked to make responses after execution by guillotine, but none of them have yielded any really firm evidence that a severed head can see or think for more than an instant after it parts company from the body.
