Silence is not the absence of communication. It is a distinct form of communication. A sustained gaze, a subtle raising of the eyebrows, a brief tightening of the lips, or an almost imperceptible change in the periocular musculature can convey an amount of emotional information that words cannot express. The face continues to communicate because the brain never ceases to process emotions, intentions, memories, and expectations, 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 silence end the science of emotion.
