Framed by the theme "Brain and Emotion – Face Connects People," the volume compiles speeches, keynote lectures, and peer-reviewed papers from world-renowned experts including A. Freitas-Magalhães, António Damásio, Joseph LeDoux, Daniel Goleman, Martin Seligman, Joan-Pere Barret, Dacher Keltner, and Lisa Feldman Barrett. The conferral of an Honorary Doctorate on LeDoux, alongside distinctive artistic performances, underscores the seamless fusion of science and emotion. This book pays tribute to the human face as both a mirror of the mind and a universal laboratory of feeling. It is an essential read for anyone who studies, practices, or is simply passionate about the brain, the face, and emotion.
