New finding about activity in brain at death

I read the entire article , seems like complex genes for memory etc diminish or shut down but those with “clean up duties” become activated . I’m not smart enough to know if “genes” activating has anything to do with a person forming thoughts or memories etc ... but could this “finding” be used by some to suggest “who knows what else happens at time of death with the brain that we don’t know that could explain NDE’s.”

'Zombie genes' come alive for many HOURS after a person dies
