I believe some things about cellular and neural activity are about bi-stable states of being. You expend energy holding state A and can be in state B by changing expenditure of energy.<p>If you disrupt neural and oxygenated blood flow, there would be an initial pressure and energy drop. But, clearly most cells get a simultaneous uh-oh kick. If it took about 60 seconds for them to hold back the change from intra cellular holdings and then flip state, I would not be surprised.<p>Muscle meat takes longer to shed its lactic acid burden. That's what meat hanging is about. I'm told you can see muscle twitches in hung carcases for some time.<p>Van Jacobson's work on TCP included the network effect of buffer and delay causing window synchronisation. You would think a brain might also be forced into a co-aligned state by a single massive all encompassing trauma like loss of oxygenated blood in one stroke (sorry)
