The evolution of the Facial Action Coding System, from muscular coding to neural facial coding, has redefined how we understand human emotion, argues Prof. Freitas-Magalhães, the world's leading expert for Neuroscience and Biobehavioral Psychology and the Encyclopedia of Human Behavior, by Elsevier, Oxford, in his pioneering and extraordinary book on the history and science of FACS, in which he presents the historical transition from 1978 to F-M FACS 6.0 (2026), the introduction of a neural nomenclature - NAUs, NADs, NMVs, NGBs, NVCs and NVOi - the development of F-M MedFACS 5.0 for medical application, and the recognition of Love as the ninth basic emotion.
