Hypoxic ischemic encephalopathy ( HIE ) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total.
Brain researchers in Paris have been working to better understand these cascading changes that occur when a brain is deprived of oxygen, as well as what they mean for our conceptualization of death.
