A replay of life: What happens in our brain when we die?
Imagine reliving your entire life in the space of seconds. Like a flash of lightning, you are outside of your body, watching memorable moments you lived through. This process, known as ‘life recall’, can be similar to what it’s like to have a near-death experience. What happens inside your brain during these experiences and after death are questions that have puzzled neuroscientists for centuries.
Since Sigmund Freud, therapists have been exclusively hunting for trauma events which Silvia Hartmann argues is looking in the completely wrong direction. Indeed, in Hartmann's Star Matrix book, she says that it's only these high energy positive moments in our lives that guide us, shape who we are and ultimately the only memories we remember when "our life flashes before our eyes".
A new study published to Frontiers in Aging Neuroscience suggests that Hartmann is indeed correct. What you see when you shut your eyes for the last time is the compliments, not the insults. It's love, not hate. It's joy, not sadness. It's pride, not regret.
Neuroscientists have recorded the activity of a dying human brain and discovered rhythmic brain wave patterns around the time of death that are similar to those occurring during dreaming, memory recall, and meditation. Now, a study published to Frontiers brings new insight into a possible organizational role of the brain during death and suggests an explanation for vivid life recall in near-death experiences.
When an 87-year-old patient developed epilepsy, Dr Raul Vicente of the University of Tartu, Estonia and colleagues used continuous electroencephalography (EEG) to detect the seizures and treat the patient. During these recordings, the patient had a heart attack and passed away. This unexpected event allowed the scientists to record the activity of a dying human brain for the first time ever.
Findings ‘challenge our understanding of when exactly life ends’
“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 Ajmal Zemmar, a neurosurgeon at the University of Louisville, US, who organized the study.
“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.”
Brain oscillations (more commonly known as ‘brain waves’) are patterns of rhythmic brain activity normally present in living human brains. The different types of oscillations, including gamma, are involved in high-cognitive functions, such as concentrating, dreaming, meditation, memory retrieval, information processing, and conscious perception, just like those associated with memory flashbacks.
“Through generating oscillations involved in memory retrieval, the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences,” Zemmar speculated. “These findings challenge our understanding of when exactly life ends and generate important subsequent questions, such as those related to the timing of organ donation.”
A source of hope
While this study is the first of its kind to measure live brain activity during the process of dying in humans, similar changes in gamma oscillations have been previously observed in rats kept in controlled environments. This means it is possible that, during death, the brain organises and executes a biological response that could be conserved across species.
These measurements are, however, based on a single case and stem from the brain of a patient who had suffered injury, seizures and swelling, which complicate the interpretation of the data. Nonetheless, Zemmar plans to investigate more cases and sees these results as a source of hope.
Dr Ajmal Zemmar, Neurosurgeon writes:
As a neurosurgeon, I deal with loss at times. It is indescribably difficult to deliver the news of death to distraught family members.
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.
Maybe death isn't the end
Following on from the study, it's interesting to ask why the human brain appears to be hard wired to process high-positive Star Memories before death.
Silvia Hartmann, author of Star Matrix writes:
20 years ago I became interested in the "life flashing before your eyes" events of people and it took a while before I realised that trauma doesn't flash - "at the end of the day, trauma counts for NOTHING."
I feel strongly that this event is an "upload" into the soul, a final update to make sure all the events from this life are "saved" not in the cloud, but in the StarFields. But whether this is true or not is entirely irrelevant. What is relevant for THIS LIFE is that we should focus on the Star Events, pay attention to them, learn from them, share them with each other, and put them into the centre of our existence, instead of obsessing endlessly over trauma.
It is our Star Events that define us, that are our lives.
