Is the Sensorimotor Cortex Relevant for Speech Perception and Understanding? An Integrative Review

Malte R. Schomers, Friedemann Pulvermüller
2016 Frontiers in Human Neuroscience  
We conclude that frontoparietal cortices, including ventral motor and somatosensory areas, reflect phonological information during speech perception and exert a causal influence on language understanding  ...  In particular, acoustic noise during the experiment and 'motor noise' caused by button press tasks work against the frontoparietal manifestation of phonemes.  ...  Radoslaw Cichy and our referees for helpful discussion.  ...

Decoding Speech for Understanding and Treating Aphasia [chapter]

Brian N. Pasley, Robert T. Knight
2013 Progress in Brain Research  
The focus of this framework is a quantitative, model-based characterization of speech and language neural representations that can be used to decode, or predict, speech representations from measured brain  ...  Aphasia is an acquired language disorder with a diverse set of symptoms that can affect virtually any linguistic modality across both the comprehension and production of spoken language.  ...  We next investigated the relationship between motor cortex ECoG activity and the average gestural scores of speech articulators during phoneme production.  ...

2015 Frontiers in Neuroscience  
These findings also confirm that the function of the premotor area is predominantly motor in nature and its sensory responses is more consistent with the "sensory theory of speech production," in which  ...  it was proposed that sensory representations are used to guide motor-articulatory processes.  ...  Acknowledgments Authors thank Aya Sato for taking part in the classification of articulatory disturbance. We also thank Jun Tanji and Atsushi Yamadori for valuable comments on the manuscript.  ...

From gestural pointing to vocal pointing in the brain

Hélène Lœvenbruck, Coriandre Vilain, Marion Dohen
2008 Revue Française de Linguistique Appliquée  
The role of index-finger pointing in language acquisition suggests that it may be a precursor of vocal pointing or that vocal pointing may be grounded in the same cerebral network as gestural pointing.  ...  Pointing is involved at different stages of human communication development, in multiple modalities: first with the eyes, then with the finger, then with intonation and finally with syntax.  ...  Then at 16 to 20 months, during the transition from the one-word stage to the two-word stage, combinations of words and deictic gestures can be observed (such as a pointing gesture to a location and pronouncing  ...
