Comprehending body language and mimics: an ERP and neuroimaging study on Italian actors and viewers.

In this study, the neural mechanism subserving the ability to understand people's emotional and mental states by observing their body language (facial expression, body posture and mimics) was investigated in healthy volunteers. ERPs were recorded in 30 Italian University students while they eva...
