In search of neural bases of pantomimes: fMRI evidence
| Resumo: | As every neural process that happens in the human brain, gesture recognition is not of easy understanding. Controversial results have been found in the literature regarding the neural bases recruited for the recognition of non-object related gestures. With that in mind, we have now tried a distinct approach on the study of gestures hoping to unfold the mechanisms behind pantomimes’ recognition. The present paradigm consisted in the observation of pantomime and intransitive gestures performed either oriented towards the body (e.g. “using lipstick”) or away from it (e.g. “driving a car”). Globally, we found increased activity in the anterior regions for the two gestures presented towards the body, and a more posterior activation for those away from the body. Additionally, we found that pantomimes and intransitive gestures are recruiting distinct neural. Results unveiled a more left-lateralized activation for pantomime observation, while intransitive gestures produced a more widespread pattern of activation along the brain. More specifically, pantomimes toward the body require the involvement of parietal regions (e.g. precuneus and inferior parietal gyrus) whilst pantomimes away activate occipital areas (e.g. fusiform and lingual gyrus). |
