Brain activity may continue for more than 10 minutes after the body appears to have died, according to a new study. Canadian doctors in an intensive care unit appear to have observed a person’s brain continuing to work even after they were declared clinically dead. In the case, doctors confirmed their patient was dead through a range of the normal observations, including the absence of a pulse and unreactive pupils. But tests showed that the patients’ brain appeared to keep working – experiencing the same kind of brain waves that are seen during deep sleep.
