Contribution of the basal ganglia to spoken language: is speech production like the other motor skills?
Abstract
Two of the roles assigned to the basal ganglia in spoken language parallel very well their contribution to motor behaviour: (1) their role in sequence processing, resulting in syntax deficits, and (2) their role in movement "vigor," leading to "hypokinetic dysarthria" or "hypophonia." This is an additional example of how the motor system has served the emergence of high-level cognitive functions, such as language.
