![]() ![]() "Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations, so-called gamma oscillations, but also in others such as delta, theta, alpha and beta oscillations."īrain oscillations (more commonly known as "brain waves") are patterns of rhythmic brain activity normally present in living human brains. ![]() Ajmal Zemmar, a neurosurgeon at the University of Louisville, US, who organized the study. "We measured 900 seconds of brain activity around the time of death and set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating," said Dr. This unexpected event allowed the scientists to record the activity of a dying human brain for the first time ever.įindings 'challenge our understanding of when exactly life ends' During these recordings, the patient had a heart attack and passed away. Raul Vicente of the University of Tartu, Estonia and colleagues used continuous electroencephalography (EEG) to detect the seizures and treat the patient. When an 87-year-old patient developed epilepsy, Dr. However, a new study suggests that your brain may remain active and coordinated during and even after the transition to death and may even be programmed to orchestrate the whole ordeal. What happens inside your brain during these experiences and after death are questions that have puzzled neuroscientists for centuries. This process, known as "life recall," can be similar to what it's like to have a near- death experience. Like a flash of lightning, you are outside of your body, watching memorable moments you lived through. It’s a common neurological process that can pretty much happen to anyone who experiences a near-death event.Imagine reliving your entire life in the space of seconds. The study suggests that an LRE is not a mystical event that happens to special people. They found that all of these experiences trigger common neurocognitive mechanisms that happen every day – but in a more highly concentrated way. In their study, the researchers compared LRE occurrences to those of people who had non-trauma-related but similar experiences such as “déjà vu” or who feel regret about past events. These parts of the brain also are vulnerable to hypoxia and blood loss that can occur in the event of a traumatic, near-death experience. ![]() To figure out why this phenomenon occurs, neuroscientists studied the prefrontal, medial temporal and parietal cortices of the brain, which all are associated with housing autobiographical memories.
