“A team of scientists inadvertently recorded the brainwaves of an 87-year-old patient as he died, providing the first glimpse at what happens in the brain during the final moments of life.
The man’s brainwave patterns in the 30 seconds before and after his heart stopped beating were similar to what occurs during dreaming, memory recall, and meditation.
The man was in the hospital after developing epilepsy after a fall. While doctors were using continuous electroencephalography (EEG) to detect his seizures and treat him, the man had a heart attack and died.
Around the time of death, the EEG recorded changes in gamma brainwaves (oscillations) and other types of brainwaves.”
