TY - JOUR ID - citeulike:4861710 L3 - citeulike-article-id:4861710 N2 - Accurate perception of the actions and intentions of other people is essential for successful interactions in a social environment. Several cortical areas that support this process respond selectively in fMRI to static and dynamic displays of human bodies and faces.
