0.2秒的微表情（Micro Expression）- 大脑的使用会显示在脸部肌肉系列4 (Paul Ekman) 微表情是指人们在受到内心真实情绪触动时，下意识想要压抑或掩饰，大脑的边缘系统（Limbic System）会通过 7 个特定信号(快乐、悲伤、愤怒、害怕、厌恶、轻蔑、惊讶)在脸上瞬间闪过、通常只维持 0.2秒到0.5秒（甚至短至1/25秒）的极短暂微细表情变化。 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).
