Abstract(in English) | External pacing such as metronome sound is known as having fluency-inducing effect on speech-related disorders like stuttering. The neural mechanisms of this effect have not been investigated sufficiently. We measured event related de-synchronization (ERD) with magnetoencephalography (MEG) when the subject performed either vocalization, or observation of video of vocalization. Transforming the measured signal to time-frequency representation, the ERD (~10 and 20 Hz) when vocalizing with pacing was largely observed than without pacing. The ERD when just looking at video of vocalization also caused ERD at the timing of vocalization. These results suggest that the effect of external pacing on people who stutter could be explained as the activation modulation of neural circuit of speech motor control. Furthermore, the specifying of vocalization related ERD has possible applications of Brain Machine Interface (BMI) for communication. |
