  • The amygdala has long been thought to play an important part in the processing of emotions, particularly fear, though its exact role was unknown. Brain imaging studies show amygdala activity during fear, but what those studies can't tell is "whether it is absolutely necessary for the experience," says Mike Koenigs, a neurobiologist at the University of Wisconsin-Madison. It's possible, he says, that the amygdala activity is a result of processes in other brain structures, without being essential to the feeling. Here, Aschwanden discusses why understanding some people's lack of fear on anything could explain how terror is being processed.
