Title: "Neural processing of variation in speech: the role of action observation and motor imagery"

Abstract:

 

Everyday interaction rarely happens in optimal listening conditions. Generally, our perceptual system needs to deal with a wide variety of distortions in the incoming acoustic signal, such as background noise, or an unfamiliar regional or foreign accent. However, some current models addressing the neural organisation of speech suggest that the brain generates forward models to support prediction of ongoing and upcoming speech actions. Forward models can be characterised as internal simulations running in parallel with the incoming auditory signal. Different models for action (including  speech) processing do not agree on whether forward models are generated action observation or during motor imagery. Our lab's research programme of the last five years investigated the role of articulatory primary motor cortex during action observation and motor imagery during speech perception and production. Our ultimate aim is to clarify the characteristics of forward models thought to be generated during action observation and motor imagery processes during speech processing. Action observation of speech refers to passive perception of observed speech actions. Motor imagery of speech involves silent articulation of speech actions that requires attentional processing. I will discuss a series of experiments in which we used TMS to probe the relative excitability of articulatory areas in primary motor cortex during perception of distorted syllables using Motor Evoked Potentials (MEPs) and during motor imagery of simple and more complex speech actions. I will discuss the results of our MEP experiments in the context of current neurobiological models of speech and action processing. 

ALL ARE WELCOME
