Consolider-CogNeuro Seminar Series

Investigating auditory-motor processing of speech sounds using transcranial magnetic stimulation.

Rikka Mottonen, Department of Experimental Psychology at the Oxford University.

Invited by Salvador Soto.

 

Abstract:

The link between speech perception and production is still poorly understood. Growing 
evidence shows that regions in the motor cortex that control the movements of the 
articulators (e.g., lips) activate during listening to speech. Whether these motor regions 
contribute to speech perception is under active debate. Transcranial magnetic stimulation 
(TMS) provides a powerful tool to investigate the role of the articulatory motor cortex in 
speech perception. In this talk, I will first present evidence that TMS-induced disruption of the 
lip motor representation impairs discrimination of speech sounds that differ in the place of 
articulation, supporting the idea that the articulatory motor cortex contributes to speech 
perception. I will then present evidence that the TMS-induced disruption of the lip motor 
representation modulates early auditory-cortex responses to speech sounds measured using 
electro- and magnetoencephalography. I will argue that these findings show that the auditory 
and motor cortex interact during speech processing. I will also discuss the effect of attention 
on these auditory-motor interactions.
