Résumé

The human tendency to imitate gestures performed by conspecifics is automatic in nature. However, whether this automatic imitation can be considered as a true imitative phenomenon or only as a special instance of spatial compatibility is still being debated. New evidence suggests that automatic imitation, otherwise known as 'imitative compatibility', shall be considered as a phenomenon that operates independently from spatial compatibility. So far there are only a few investigations directly aimed at identifying the neural structures dedicated to this process. In the present study, we applied double-pulse transcranial magnetic stimulation (TMS) over the parietal opercula to further investigate the role of these regions in coding imitative compatibility. We found that a temporary disruption of parietal opercula caused the reduction of the imitative compatibility relative to the sham condition. In particular , the TMS interference with the parietal opercula's activity modulated the imitative compatibility but not the spatial compatibility , suggesting that these two processes are likely to be independent.
