Beyond Broca: Neural Architecture and Evolution of a Dual Motor Speech Coordination System
[post]

Preserved Fulltext
Classical neural architecture models of speech production propose a single system coordinating all the vocal articulators from lips to larynx. Here we propose a dual coordination system in which laryngeal control of pitch-related aspects of prosody and song are controlled by a dorsal premotor system while supralaryngeal articulation at the phonetic/syllabic level is controlled by a ventral premotor system. The separability of these neural systems supports models of the evolution of speech and
