sentences:  Participants watched video clips of happy, sad, angry and disgust facial expressions, and measured their empathy quotient (EQ).Specific brain regions relevant to the four emotions were found to be correlated with the EQ while the mirror system (i.e., the left dorsal inferior frontal gyrus/premotor cortex) was correlated to the EQ across all emotions.The authors interpreted this result as an evidence that action perception mediates face perception to emotion perception.
