Neural control of speech movements

摘要: Controlling speech movements for producing the syllables that make up a spoken utterance requires complex integration of many different types information by brain, including auditory, tactile, proprioceptive, and muscle command representations. This chapter addresses these representations their interactions with reference to model neural processes involved in production sounds such as phonemes syllables. The has been developed account wide variety experimental data concerning articulator adults development speaking skills children. Neural correlates model’s components have identified, thus allowing serve framework interpreting organizing accumulating mass from functional imaging studies human brain. Before proceeding, it will be useful define some frames are believed planning movements. For present purposes, “reference frame” can thought coordinate frame best captures form represented particular part nervous system. example, motoneurons project articulatory musculature encode length frame. Interactions between brain regions transformations corresponding frames. following paragraphs several important production.
