摘要

Unlike emotions,which are short-lasting events accompanied by viscero-motor responses,vitality forms are continuous internal states that modulate the motor behaviors of individuals and are devoid of the autonomic modifications that characterize real emotions.Despite the importance of vitality forms in social life,only recently have neurophysiological studies been devoted to this issue.The first part of this review describes fMRI experiments,showing that the dorso-central insula is activated during the execution,the perception and the imagination of arm actions endowed with different vitality forms as well as during the hearing and the production of speech conveying vitality forms.In the second part,we address the means by which the dorso-central insula modulates the networks for controlling action execution and how the sensory and interoceptive information is conveyed to this insular sector.Finally,we present behavioral data showing the importance of vitality forms in social interactions.
