Neural basis of pantomime and intransitive gestures: an fMRI study

View document

Bibliographic Details
Summary:Previous neuroimaging studies have found mixed and inconsistent results regarding dissociative brain networks recruited for processing pantomimes and intransitive gestures. We compared brain activation involved in the recognition of pantomime (e.g., “brushing teeth”), intransitive (e.g., “waving goodbye”) and meaningless gestures in 12 healthy subjects by using event-related fMRI. Overall, we found that recognition of pantomimes when compared to meaningless gestures was associated with an increased BOLD-activity of the right middle temporal gyrus, left cuneus and left uvula, and of the left precuneus when compared with intransitive gestures. The brain activations for intransitive gestures when compared to meaningless gestures included the left superior frontal gyrus, the left precentral gyrus, the left middle temporal gyrus, the left supramarginal gyrus and the right insula, and the left medial frontal gyrus when compared with pantomimes. These findings point out that pantomimes recruit brain areas linked to semantic information, giving a meaning and storing the appropriate way of using an object, motor representation of the tool use and attentional orientation, whereas intransitive gestures were associated with activations in areas linked to social cognition. Finally, the meaningless gestures recruit brain-areas linked to motion perception.
