Neurology of Stuttering
“Of the many theoretical accounts of stuttering proposed previously, our [researchers at the University of Turku, Finland] data provide support for a crucial role of the basal ganglia. Importantly, our findings propose a specific and biologically plausible neuroanatomical circuit for stuttering centred on the posteroventral part of the left putamen, which is responsible for automation and internal timing for sequencing of complex motor movements of the lips and other articulators. The additional findings implicating the ventral claustrum and amygdalostriatal transition area in stuttering provide an important new direction in mapping the neural basis of stuttering, and ensuring the best possible diagnostic and treatment approaches can be developed.” MORE
