Abstract: In this article, we reviewed the latest researches addressing the plasticity of the emotional circuitry from two main aspects: (1) several main emotional brain regions in the circuitry (such as the prefrontal cortex and amygdala) and their interaction; (2) factors that influence the plasticity in the emotional circuitry, including emotional learning, early environment, early experience and the emotion & mood of care-taker. In the end, frequently used methods were listed and some reflections were provided for the future study

Key words: emotion, neural circuitry, plasticity, learning, early experience
