Functional activation for imitation of seen and heard speech
چکیده انگلیسی

This study examined fMRI activation when perceivers either passively observed or observed and imitated matched or mismatched audiovisual (“McGurk”) speech stimuli. Greater activation was observed in the inferior frontal gyrus (IFG) overall for imitation than for perception of audiovisual speech and for imitation of the McGurk-type mismatched stimuli than matched audiovisual stimuli. This unique activation in the IFG during imitation of incongruent audiovisual speech may reflect activation associated with direct matching of incongruent auditory and visual stimuli or conflict between category responses. This study provides novel data about the underlying neurobiology of imitation and integration of AV speech.


► Presents novel data about the underlying neurobiology of imitation of AV speech.
► Unique activation in IFG during imitation of incongruent audiovisual speech.
► Findings may reflect direct matching or conflict between category responses.
