This chapter discusses factors influencing the event-related potential signal, N170, during the perception of dynamic faces, and compares the findings of studies in cognitive neuroscience that have used dynamic images of facial expressions with those which have used static expressions. The ecological validity of findings has been increased by using dynamic images of facial expressions and gaze. The chapter emphasizes that the perceived intensity of subsequent expressions can also be modulated by the brief dynamic expressions or micro expressions, a finding which establishes a direct relationship between perception and action in facial processing. It concludes that future developments in computer animations and virtual reality, and the use of dynamic stimuli, will play a crucial role in examining the dynamic nature of perception and the underlying brain functions.

Keywords:   N170, cognitive neuroscience, micro expressions, computer animations, virtual reality
