What happens to our brains when we die? A new study could provide answers
How long after death are you aware?

How long does the heart beat after death?
The heart typically stops beating within minutes to about an hour after the final breath, though it may show electrical activity for longer. While cardiac muscles can technically twitch for a short time after death, "death" is declared when the heart stops, and circulation ceases, causing irreversible organ failure.
How do you confirm brain death?
Brain death is the irreversible cessation of all brain function, including the brainstem, confirming legal death. Diagnosis requires a known, irreversible cause of coma, absence of brainstem reflexes (pupil, gag, cough), and a positive apnea test (no spontaneous breathing). Specialized tests, such as cerebral blood flow studies, can be used if clinical exams are limited.
