In Gilligan's Island, a blow to the head can erase someone's memory, while another perfectly timed impact miraculously restores it. Movies like The Bourne Identity and countless soap operas have made sudden memory loss one of Hollywood's favorite medical mysteries. But what actually happens inside the brain during a concussion, and can physical trauma selectively erase someone's identity while leaving everything else intact? This episode explores traumatic brain injuries, hippocampal function, retrograde and anterograde amnesia, and why a second head injury is far more likely to worsen neurological damage than reverse it.
