Although the healthy adult possesses a large repertoire of coordinative strategies for oromotor behaviors, a range of nonverbal, speech-like movements can be observed during speech. The extent of overlap among sensorimotor speech and nonspeech neural correlates and the role of neuromodulatory inputs generated during oromotor behaviors are unknown. The focus of this review is to consider the adaptive capacity of the orofacial substrate, and the neural correlates of kinematic parameter encoding at cortical and subcortical levels subserving oromotor behaviors. Special emphasis is directed toward distributed neural networks that are dynamically modulated by environment and task related demands.
Readers will (1) gain a better understanding of healthy adult orofacial pathways, (2) be able to identify orofacial pathway components that contribute to sensorimotor integration, and (3) better understand the flexible connectivity among distributed neural networks subserving oromotor behavior.
尽管健康成年人拥有大量用于口面部运动行为的协调策略，但在言语过程中仍可观察到一系列非言语、类似言语的运动。感觉运动性言语和非言语神经关联之间的重叠程度以及口面部运动行为中产生的神经调节输入的作用尚不清楚。本综述的重点是考虑口面部基质的适应能力，以及在皮层和皮层下水平编码运动学参数以支持口面部运动行为的神经关联。特别强调由环境和任务相关需求动态调节的分布式神经网络。
读者将（1）更好地理解健康成年人的口面部通路，（2）能够识别有助于感觉运动整合的口面部通路成分，以及（3）更好地理解支持口面部运动行为的分布式神经网络之间的灵活连接。
