This, the inaugural volume of NeuroPeace, is a three-part series that brings together a group of eminent researchers on the frontlines of neuroscience to share—in a way that is accessible and engaging to nonscientists—their work and to spotlight how it might be relevant and useful to those who work to prevent wars, terrorism, and other forms of violent conflict and to help societies and individuals to heal in the aftermath of violence. The researchers cover a broad range of cutting-edge topics that are grouped under three broad headings and published in three separate editions: Individual Aggression (NeuroPeace no. 1), Group Dynamics (NeuroPeace no. 2), and Trauma (NeuroPeace no. 3).
