0.2秒的微表情（Micro Expression）- 大腦的使用會顯示在臉部肌肉系列4 (Paul Ekman) 微表情是指人們在受到內心真實情緒觸動時，下意識想要壓抑或掩飾，大腦的邊緣系統（Limbic System）會通過 7 個特定信號(快樂、悲傷、憤怒、害怕、厭惡、輕蔑、驚訝)在臉上瞬間閃過、通常只維持 0.2秒到0.5秒（甚至短至1/25秒）的極短暫微細表情變化。 0.2-Second Micro Expression - Brain usage will be reflected in Facial Muscles Series 4 Micro expressions refer to the extremely brief, subtle changes in facial expression that occur when people are touched by true inner emotions and subconsciously try to suppress or conceal them. The brain's limbic system sends seven specific signals (happiness, sadness, anger, fear, disgust, contempt, and surprise) that flash across the face momentarily, usually lasting only 0.2 to 0.5 seconds (or even as short as 1/25 of a second).
