Scientists in Vancouver captured the final moments of an 87-year-old epilepsy patient's life on an electroencephalogram, suggesting that the brain may relive important life memories before death. This concept is supported by observed increases in gamma oscillations, important for memory recall, in both humans and rats during the final moments.Scientists in Vancouver captured the final moments of an 87-year-old epilepsy patient's life on an electroencephalogram, suggesting that the brain may relive important life memories before death.
