In this National Geographic News article, read about research into how fear is experienced and processed. Scientists say stathmin, a gene that is normally present in high levels in a part of mammals' brains called the amygdala, controls both innate and learned fear. They found that switching off the gene makes a fearful mouse courageous. Links to other stories, photos, videos and Web sites are also found on this page.
