Many people who stutter consult speech-language pathologists (SLPs) for assistance because these professionals are experts in the anatomy, physiology, and motor systems of the speech mechanism and can provide education and behavior modification to achieve greater control over speech (Cooper, 1997).
The neurological basis of speech motor control has remained unknown until now because scientists cannot study speech mechanisms in animals and because non-invasive imaging methods lack the ability to resolve the very rapid time course of articulator movements, which change in hundredths of seconds.

Prof Robert Knight, one of the researchers from the University of California at Berkeley, said: This is huge for patients who have damage to their speech mechanisms because of a stroke or Lou Gehrigs disease and cant speak.
He suggested that this cell death could lead to a 'glitch' in the speech mechanisms, 'blocking' the ability to pronounce certain sounds and causing the stammer.
Taking a narrower view than that of MacNeilage and his collegues, Tomasello says specialized speech mechanisms, not language in general, are all that have been located in the left hemisphere.
