What we were sure about was that a comatose patient who had a flat EEG (electroencephalogram) line had a dead brain. But nowadays, it seems like a flat line didn’t meant a completely dead brain.


What we found out is that it is possible to bring a comatose patient into a deeper coma statement. Once the patient is in a more extreme coma, one part of the brain, the hippocampus, begins to reestablish itself, while the cortex, another part of the brain, stop it’s activity. The thing is, apparently, the hippocampus activity can be strong enough to tickle the cortex and can reactivate it.


For now, we still don’t know how to apply this discovery in treatments, but we know that this won’t work for all patients. For example, a victim of a car crash that had hit he’s head really bad may be a patient on which this new method won’t work, but it could work for a heart attack victim.


There are much more details about that in this article:
