So, I still don't know if you are irreversibly dead if your brain stops all activity. I.e. is the state of your brain preserved just by the connections of the neurons? Or is the "RAM" also critical?

When your brain doesn't get oxygen it will die. See https://en.wikipedia.org/wiki/Cerebral_hypoxia

ECMO is an amazing technology that's often used in futile situations. I don't know who the ideal candidate is for it, but a young, fit, hypothermic cardiac arrest victim is pretty high up on the list

I don't know about ideal, but it saved my 6 day old son so yeah, "amazing" is totally warranted. Years later I sometimes take a look at some of the pictures we took (cameras would be forbidden in ICU soon after) and stare in awe.

That's incredible! Are the pictures online anywhere?

What leads to brain damage, as I understand it, is lack of oxygen like all other organs and hypothermia reduces your brain activity and its consumption of oxygen but I always interpreted brain activity as an indicator of oxygen consumption and not as something that'd have a cause-effect relationship with brain damage.

It's more then that in this case. She had not vital signs at all, heart not beating and providing oxygen included.

How did her brain survive with seemingly no oxygen being replenished thru circulation?
