Some recall bright lights at the end of a tunnel, feeling the presence of loved ones or floating above their body after a near-death experience.Now, scientists say they have captured conscious-like brain activity in dying patients in findings that give new insights into the process of death.How vivid experience can emerge from a dysfunctional brain during the process of dying is a neuroscientific paradox, said Jimo Borjigin, of the University of Michigan, who led the study.
