Abstract
The interest of neuroscience has been aimed at the investigation of the neural bases underlying gestural communication.
This research explored the intra- and inter-brain connectivity between encoder and decoder. Specifically, adopting a “hyperscanning
paradigm” with the functional Near-infrared Spectroscopy (fNIRS) cerebral connectivity in oxygenated (O2Hb) and deoxygenated (HHb)
hemoglobin levels were revealed during the reproduction of affective, social, and informative gestures of different valence. Results showed
an increase of intra- and inter-brain connectivity in dorsolateral prefrontal cortex for affective gestures, in superior frontal gyrus for
social gestures and in frontal eyes field for informative gestures. Moreover, encoder showed a higher intra-brain connectivity in posterior
parietal areas more than decoder. Finally, an increasing of inter-brain connectivity more than intra-brain (ConIndex) was observed in left
regions for positive gestures. The present research has explored how the individuals neural tuning mechanisms turn out to be strongly
influenced by the nature of specific gestures.
