Stochastic control system of basal ganglia and relation with stuttering
نویسندگان
چکیده
In resent years, it is said that the basal ganglia has a feedback control function for motion generation. Some authors suggested that the feedback control function of the basal ganglia has something to do with language dysfunction, especially dysfunction of utterance motion like Gilles de la Tourette syndrome or stuttering. But we don’t know the concrete mechanism of the relation. We have to know what kind of computation is on going within the basal ganglia. In this paper, first we propose a view of motor area basal ganglia loop as a stochastic control system. We evaluate our model through a computer simulation for the arm movement. Next we attempt to explain stuttering based on our model. We show that dysfunction of stochastic control system of the basal ganglia may cause the stuttering.

Computational approach to stuttering
Though many causes have been considered from mental or anatomical viewpoint, the mechanism of stuttering is not known yet. One candidate for the stuttering occurrence is a dysfunction of basal ganglia. However the detailed relation between the basal ganglia dysfunction and the stuttering is not understood. In this study, based on anatomical, physiological and clinical evidences, we propose a fu...
متن کاملStuttering and the basal ganglia circuits: a critical review of possible relations.
UNLABELLED The possible relation between stuttering and the basal ganglia is discussed. Important clues to the pathophysiology of stuttering are given by conditions known to alleviate dysfluency, like the rhythm effect, chorus speech, and singing. Information regarding pharmacologic trials, lesion studies, brain imaging, genetics, and developmental changes of the nervous system is reviewed. The...
متن کاملChildhood Laryngeal Dystonia Following Bilateral Globus Pallidus Abnormality: A Case Study and Review of Literature
Introduction:Dystonia is a disorder of movement caused by various etiologies. Laryngeal dystonia is caused by the spasm of laryngeal muscles. It is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. The pathophysiology of this type of dystonia is not fully known. Some researchers have suggested that basal ganglia structure...
متن کاملStuttering: a dynamic motor control disorder.
UNLABELLED The purpose of this review is to determine what neural mechanisms may be dysfunctional in stuttering. Three sources of evidence are reviewed. First, studies of dynamic inter-relationships among brain regions during normal speech and in persons who stutter (PWS) suggest that the timing of neural activity in different regions may be abnormal in PWS. Second, the brain lesions associated...
متن کاملSimulated stuttering in non-stuttering healthy subjects: differentiating cause from consequence in developmental stuttering
Introduction Over the past decade several functional neuroimaging studies in developmental stuttering have been published. In comparison to non-stuttering volunteers, these studies revealed that adults who stutter show overactivation in areas such as the cerebellum, supplementary motor area (SMA), right frontal operculum (RFO), and the right insula. This overactivation mostly occurs bilaterally...
