The Nature of Things - Season 42 Episode 1

Bob thinks but doesn't feel. Christina feels but has trouble thinking. Virginia can neither think or feel as she's pulled down into a spiral of darkness that zaps her very will to survive. Kent lives within a 20-minute time span, unable to remember his past or plan for his future. Each of these people has had an injury to a part of the brain called the frontal lobes and their stories, told in Me, My Brain And I, are helping neuroscientists unravel the mystery of what makes us distinctly human.
