  "abstract": "<p>People communicate using speech, gestures, and, less frequently, touches. An example of tactile<br>\ncommunication is represented by handshake. Customs surrounding handshake vary in different<br>\ncultures. In Western societies is mostly used when meeting, parting, as a sign of congratulations or at<br>\nthe end of a successful business. Despite its importance in social life, the neural mechanism underlying<br>\nthe affective components conveyed by handshake (&ldquo;tactile vitality forms&rdquo;) is unknown. Here we<br>\ncombined functional magnetic resonance imaging (fMRI) and electromyography (EMG), to investigate<br>\nthe neural affective activations during handshakes. We demonstrated that handshake conveying<br>\ngentle or aggressive tactile vitality forms produces a stronger activation of the dorso-central insula.<br>\nThe simultaneous presence of emotional facial expressions modulates the activation of this insular<br>\nsector. Finally, we provide evidence that the cingulate cortex is involved in the processing of facial<br>\nexpressions conveying different vitality forms.</p>",
