In other areas of the brain, viable human neurons have been recovered and grown in culture hours after clinical death. [10] Brain failure after clinical death is now known to be due to a complex series of processes called reperfusion injury that occur after blood circulation has been restored, especially processes that interfere with blood ...
Brain death is used as an indicator of legal death in many jurisdictions, [6] but it is defined inconsistently and often confused by the public. [7] Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations.
Per the United Kingdom Medical Royal Colleges, a diagnosis of brain death is a two-fold process including 1) identifying the cause of irreversible brain damage and excluding reversible causes of brain damage and 2) conducting a series of clinical and laboratory tests to assess brain stem function.

Scientists have managed to make death even scarier. According to a team of scientists in New York, the human brain is still very active after death, which means there's a chance you could actually ...
The brain doesn’t shut off like a light switch, even as death approaches. While other bodily organs—namely the heart and lungs—have sudden stops, the brain flickers on through active neurons ...
Initially, death was defined as occurring when breathing and the heartbeat ceased, a status still known as clinical death. [12] However, the development of cardiopulmonary resuscitation (CPR) meant that such a state was no longer strictly irreversible. [13] Brain death was then considered a more fitting option, but several definitions exist for ...
It occurs in the hours and days following the primary injury [9] [10] and plays a large role in the brain damage and death that results from TBI. [10] Unlike in most forms of trauma a large percentage of the people killed by brain trauma do not die right away but rather days to weeks after the event. [11]
DHCA is a form of carefully managed clinical death in which heartbeat and all brain activity cease. When blood circulation stops at normal body temperature (37 °C), permanent damage occurs in only a few minutes. More damage occurs after circulation is restored. Reducing body temperature extends the time interval that such stoppage can be ...
