The scientists rubbed their eyes in amazement. The 87-year-old’s brain was active as if he was remembering something, even though the senior’s heart had stopped forever half a minute earlier. The surprising results were recorded during the EEG examination of a patient suffering from epilepsy.
- Observation of the EEG has shown that dying is a process similar to that which occurs during sleep, meditation, or forceful recall
- The brain’s electrical activity suggests that the organ may recall important or pleasant events in its life just before it dies
- The results obtained in rats suggest that this may be a common neurological reaction to death in mammals

An 87-year-old man was admitted to a clinic in Louisville, USA, in whom a fall down the stairs caused an epilepsy, associated with swelling and bleeding in the brain. Doctors connected the senior to encephalography equipment, which allows to determine which forms of treatment will be the most appropriate. It turned out that the equipment recorded, among others The last 30 seconds before death and 30 seconds after the man’s heart stopped beating. The obtained results amazed the researchers. It turned out that dying is a process similar to what happens when you sleep, meditate, or remember something.

“Through the emission of waves related to recalling memories, the brain can, just before death, recreate a record of important events in life” — notes study author Dr. Ajmal Zemmar, a neurosurgeon at the University of Louisville in Kentucky, quoted in the press release.
At the same time, scientists warn against too far-reaching conclusions. Based on the examination, it is impossible to say what exactly the deceased thought just before his death. At the same time, doctors point out that due to the fall and epilepsy, certain areas of the brain could be damaged, which could affect its electrical activity.
Scientists have long studied the electrical activity of the brain during the transition between life and death. When examining laboratory rats, Michigan academics drew attention to the fact that in the first 30 seconds after the heart stopped beating, all rats showed an increase in brain activity associated with very high stimulation of this organ.
The brain remembers the “sweetest moments” it has experienced
“In fact, just before death, many of the electrical markers of awareness were above the levels known from the waking state, suggesting that the brain is capable of well-organized electrical activity in the early stage of clinical death » — notes Dr. George Mashour, Assistant Professor of Anaesthesiology and Neurosurgery at the University of Michigan in a published research release.

Similar results were obtained during the EEG tests of seven critically ill patients who died shortly afterwards. Scientists noted an increase in electrical activity in the brain even when no detectable blood pressure was present. These results may suggest that there may be a common neurological reaction to death that occurs in different species, at least among mammals.
“From this research, we can learn that although our loved ones are closed-eyed and willing to leave us, their brains can recreate the best moments they have experienced in their lives.” — Dr. Zemmar concludes.
