Pain, long regarded as a subjective and elusive experience, gains a new scientific language in this pioneering volume that introduces facial neuromicroexpressions as clinical biomarkers of neuropathic pain. Through empirical validation using the F-M FACS 5.0 system and the DN4 scale, this work bridges the gap between silent suffering and scientific objectivity.This volume defends 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 to chart the emotional and neurocognitive map of pain through the human face.
