Brainwaves
When an 87-year-old patient developed epilepsy, doctors in Estonia used EEG (a way of measuring electrical brain activity) to detect the seizures and treat the patient. But during that examination, the patient suffered a heart attack and died. This is how the brain activity of a dying human brain was recorded for the first time.
As it turns out, just before and even after the heart stopped working, changes were seen in a specific kind of brain waves (rhythmic patterns of brain activity), called gamma waves. These waves occur during, for example, studying and other forms of cognitive processing.
Last memory
Other brainwave patterns, such as those linked to dreams, memory retrieval and memory flashbacks, were also present around the time of death. That could explain the vivid memories of major life events that people with near-death experiences report.

So even shortly after your death, the brain still seems to play an important organizational role. American Dr Ajmal Zemmar, who organized the research, explains: “By generating brain waves involved in memory retrieval, the brain may play a final memory of important life events just before we die, similar to the events reported in near-death experiences.”
Promising
This study is the first to measure brain activity during death in humans, but something similar has been concluded in rat studies. It is of course true that only one patient was involved in this study, and also one with a brain that had been damaged during the epileptic seizures.
Still waiting for more research, but according to Zemmar it can be a hopeful thought: “Our loved ones may have their eyes closed and are ready to leave the world, but their brains may have the most beautiful memories of their lives. life off.”
