Decapitation
The brain of a decapitated person continues to produce brain waves
recordable by EEG 3-8 seconds after the head is severed. Is the person
conscious?
A study (Mikeska and Klemm, 1975) reported an EGG trace in the
decapitated heads of rats of up 30 seconds (on average - 14 seconds).
Allred and Berntson (1986) and Vanderwolf et al. (1988) dismissed that
as LVFA (low voltage fast activity), not necessarily indicative of
consciousness or distress. Holson (1992) reviewed the literature and
found that decapitation triggers 2-4 seconds of slow direct current
EEG trace followed by 10-13 seconds of an LVFA trace. When the rats
were anesthetized the LVFA trace lasted longer - proving that it had
nothing to do with consciousness.
Still, numerous anecdotes recounted by eyewitnesses support the theory
that consciousness survives in the first 2-6 seconds and that some
decapitated persons even realize their predicament to their utter
horror.
