I wish there were more details of the brain activity in those 3 days where she 'came back from the dead' and if there are, I wish the article had shared them. Cooling seems to be a driving factor, but was there anything else going on in her brain during that time (subconsciously perhaps) that can be seen through scans or such? Hopefully the practice of trying to revive people for longer periods of time becomes standard throughout medical practices--it'd hopefully save many lives and also perhaps reveal what is actually happening (in not just the brain, but the entire body) throughout the process and how to truly revive an individual if possible--and maybe when it is appropriate.
I've heard of this general concept several times before (coming back from the dead) as there are countless stories of people seemingly dying but becoming fully conscious after varying periods of time; however, this is the first time I heard about cooling being a considerable factor. It fascinates me because it must mean there are several unearthed factors that could potentially save millions of lives.
