The brain appears to remain active and coordinated, even as death approaches, according to doctors who analysed the first-ever recording of brain waves as a person dies.

US neuroscientists accidentally made the recording while using electroencephalography (EEG) to detect and treat seizures in an 87-year-old man who had had an MI.
