Does your life really flash before your eyes

The researchersвЂ™ survey of the EEG measurements found a decrease in the theta activity and an increase in gamma just prior to the patientвЂ™s death. He added, вЂњJust 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.вЂќ Ajmal Zemmar, a neurosurgeon at the University of Louisville, Kentucky in the U.S., who organized the study said in a statement. вЂњWe 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,вЂќ said Dr. Different types of oscillations indicate different types of brain activity including dreaming, concentrating, processing, and remembering. The oscillations are given Greek letter designations like alpha, beta, gamma, delta, and theta waves. These brain waves are part of normal human brain functioning. It is the first time the activity of a dying human brain has ever been documented. However, the EEG was still recording and captured the entire death process. The patientвЂ™s deterioration and death all happened unexpectedly. After a discussion with family members and in consideration of the patientвЂ™s вЂњDo Not ResuscitateвЂќ status, the team administered no further treatment and he died. The patient worsened suddenly and suffered a heart attack. The researchers report that an 87-year-old patient was stable for two days after surgery. Subdural hematomas can be life-threatening and typically require surgical intervention. In the case of this patient, the EEG was being used to monitor seizures while the patient was recovering during treatment for an acute subdural hematoma, a serious condition where blood collects between the skull and the surface of the brain after a head injury. The EEG monitors brain activity more formally known as brain oscillations, often called brain waves. Raul Vicente of the University of Tartu, Estonia, and colleagues was treating an 87-year-old male patient suffering from epilepsy using a technique called continuous electroencephalography (EEG). The research might be described as accidental, much like finding an archeological trove in a backyard or an unprecedented set of dinosaur bones on a hike after a storm.Дr. TWH вЂ“ The old maxim that your life flashes before your eyes before death might actually be true according to researchers who, by chance, picked up unusual brain patterns on a dying patient.
