Is this precisely because it wasn’t pure nitrogen?
Nah, as the brain dies, it gets “damaged”, and that can lead to seizures or whatever. It doesn’t really matter why it’s dying; as long as it stays more or less together, there will be “abnormal activity” until it runs out of energy and the neurons finally depolarize. During “natural death”, the whole body is usually too weak, or too sedated, to show any sign of that, but in otherwise able-bodied individuals… death ain’t pretty.
Then the question is whether the seizures would wake one from a nitrogen knockout. ie would one be aware of the seizures?
