The first recording of what happens in the brain of a dying human being .. amazing results
In the first study of its kind, neuroscientists succeeded in recording the activity of a dying human brain and discovered rhythmic brain wave patterns around the time of death similar to those that occur during dreaming, memory retrieval and meditation.
The study provides new insight into the brain's potential regulatory role during death, and suggests an explanation for life recall in NDEs.
The study, the results of which were published by "Metro" and "RT", explains that it is like you live your whole life in a matter of seconds, "like a flash of lightning, you are outside your body, and you witness unforgettable moments in which you lived."
The scientists pointed out that this process is known as "life retrieval", and could be similar to what is known as a near-death experience.
What happens inside the brain during these experiences and after death are questions that have puzzled neuroscientists for centuries.
However, the new study suggests that the brain may remain active and coordinated during the transition to and even after death, and may be programmed to regulate the entire ordeal.
The study was based on data from a patient who had epilepsy. Dr. Raul Vicente of the University of Tartu, Estonia, and colleagues used electroencephalography (EEG) when the 87-year-old patient developed epilepsy, to detect seizures and treat the patient.
During these recordings, the patient had a heart attack and died.
This unexpected event allowed scientists to record the activity of a dying human brain for the first time ever.
وتمكن العلماء من تسجيل 15 دقيقة من نشاط الدماغ خلال وفاتها. وما وجدوه كان مثيرا للغاية. وبالتركيز على 30 ثانية قبل وبعد توقف قلب المريضة عن النبض، اكتشفوا زيادة في موجات الدماغ المعروفة باسم تذبذبات غاما. وتشارك هذه الموجات في أنشطة مثل التأمل واستعادة الذاكرة والحلم.
ويقول الفريق إن النتائج «تتحدى فهمنا لمتى تنتهي الحياة بالضبط»، وأوضح الدكتور أجمل زمّار، جراح الأعصاب بجامعة لويزفيل بالولايات المتحدة، المؤلف الرئيسي للدراسة: «قمنا بقياس 900 ثانية من نشاط الدماغ في وقت قريب من الوفاة وحددنا تركيزا دقيقا للتحقيق في ما حدث في 30 ثانية قبل وبعد توقف القلب عن النبض».
وأضاف: «قبل وبعد توقف القلب عن العمل مباشرة، رأينا تغييرات في نطاق معين من التذبذبات العصبية، ما يسمى تذبذبات غاما ولكن أيضا في تذبذبات أخرى مثل دلتا وثيتا وألفا وبيتا».
Brain oscillations (more commonly known as brain waves) are patterns of rhythmic brain activity normally found in living human brains.
Different types of oscillations, including gamma, are involved in higher cognitive functions, such as concentration, dreaming, meditation, memory retrieval, information processing, and conscious perception, just as those associated with memory retrieval.
Zammar speculated: “By generating oscillations involved in memory retrieval, the brain may play the last recall of significant life events just before our death, similar to those reported in NDEs.
These findings challenge our understanding of exactly when life ends and generate important subsequent questions, such as those regarding the timing of organ donation.”
While this study is the first of its kind to measure living brain activity during the dying process in humans, and scientists have made it clear that we can't say for sure whether dying people really see their life tape before their eyes, this particular study seems to support the idea.
Scientists say the brain is able to coordinate activity for a short time even after blood stops flowing through it.
Dr. Zammar and his team stress that more research is needed before any definitive conclusions can be drawn.
This study arises from data on one case study only.
The patient's brain was already infected and was showing unusual activity related to epilepsy.
Therefore, it is not clear whether the same results would occur in someone else's brain at the time of death.
Dr. Zammar noted, "The most important thing we may learn from this research is: Although our loved ones close their eyes and are ready to leave us, their brains may be replaying some of the most beautiful moments in their lives."
