“One thing we can learn from this research is that even though our loved ones are with us, closed eyestheir brains may be reproducing some of the best moments they lived In their lifes“said the doctor ajmal zemmarneurosurgeon of the University of Louisville, United Statesand one of the doctors who organized the study.
What happens in the brain after death?: how was the study
It all started with a group of neuroscientists from the University of Tartuin Estoniawho recorded the brain activity of a 87 year old dying patientwhich had epilepsyand found some rhythmic wave patterns similar to what happens During the dream and meditation.

During the treatment of his episodes, the experts performed a electroencephalogram to detect their seizures and treat the patient. But during these recordings, the man he had a heart attack and died. It was this unexpected event that allowed scientists to record the activity of a dying human brain for the first time.
“We measured about 900 seconds of brain activity after the time of death and were able to establish a specific approach to investigate what happened in the 30 seconds before and after the heart stopped beating”said Dr. Zemmar.

“Just before and after the heart stopped working, we saw some changes in a specific band of neural oscillations, the so-called gamma oscillationsbut also in others such as delta, theta, alpha and beta oscillations”, he added.
The brain oscillationsalso known as “brain waves”They are patterns of rhythmic brain activity, present in living human brains. Different classes of oscillations, including gamma, are involved in highly cognitive functionsas are the concentrationthe sleepthe meditation, the memory recoverythe information processing and the conscious perception. This same happens with the flashbacks of the memory.

What happens in the brain after death?: conclusions of specialists
Following the study, Zemmar stated that, “through the generation of oscillations involved in memory retrieval, the brain may be reproducing a last recollection of important life events just before dying”, which would confirm the testimonies of people who lived near-death experiences.
“These findings challenge our understanding of exactly when life ends and they generate important questions for us later, such as those related to the moment of the organ donation”, he maintained at the end.
