The oscillations are also associated with memory retrieval and flashbacks - supporting the idea that “your life flashes before your eyes” in the moments before death. Gamma oscillations are involved in high-cognitive functions, such as dreaming and information processing involving extreme concentration. “We set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating.”Ī study of the EEG recording reveals that there was an increase in gamma oscillations - also known as “brain waves” - in the final seconds before the man passed away. “We measured 900 seconds of brain activity around the time of death,” Zemmar said. It shows an uptick in gamma oscillations, commonly known as “brain waves.” Frontiers in Aging Neuroscience This image of the dying man’s brain was included in the study. While the man’s brain was being recorded with EEG, he suffered a heart attack and passed away, allowing scientists to examine what happened to the organ in the moments before and after his death. The study, published Tuesday in the journal Frontiers in Aging Neuroscience, is based on one of the first recordings of a dying brain, which occurred accidentally at a hospital in Vancouver.Īn 87-year-old man was admitted to the facility following a fall, with neuroscientists hooking him up to electroencephalography (EEG) technology to detect seizures.ĮEG involves electrodes being placed along a patient’s scalp in a bid to measure activity in different parts of the brain. Ajmal Zemmar, the study’s co-author, said in a statement. “Something we may learn from this research is: Although our loved ones have their eyes closed and are ready to leave us to rest, their brains may be replaying some of the nicest moments they experienced in their lives,” Dr. South Africa mine dam wall collapse kills one and injures 40ĭear Abby: I found my biological mother and brothers, they want nothing to do with meĪ groundbreaking new study has shed light on what happens in our bodies in the moments before and after we die.īrain activity similar to meditation, dreaming or memory recall passes over the brain in its final moments, the study found, suggesting there may be a final feeling of serenity as humans pass away.
