DESCRIPTION (adapted from applicant's abstract) The research described in this proposal focuses upon the coordination of respiratory, vocal organ, and craniomandibular motor programs in producing the complex learned vocalizations of songbirds and parrots. Using neuroanatomical and physiological approaches, the research plan addresses five specific hypotheses: 1) that crystallized motor programs for both the respiratory and vocal organ muscle components of adult song can be modified by feedback from the periphery only if the vocalizations are learned; 2) that this sensory feedback arises from mechanoreceptive, proprioceptive, or thermal receptors in the vocal tract or respiratory system, and that auditory feedback is not necessary; 3) that compensatory motor responses after perturbations of respiratory pressure first appear during the plastic phase of song learning during the process of matching the output to a model syllable; 4) that respiratory and vocal organ motor neurons receive inputs from a common premotor source; 5) that, in achieving vocal complexity, parrots rely on increased plasticity in their respiratory and craniomandibular motor patterns to offset the limitations imposed by a simpler tracheal syrinx.

描述（改编自申请人的摘要） 本提案中描述的研究重点是协调 呼吸、发声器官和颅颌运动程序 鸣禽和鹦鹉复杂的习得发声。使用神经解剖学 和生理学方法，该研究计划涉及五个具体的 假设：1）具体化了呼吸和呼吸系统的运动程序 成人歌曲的发声器官肌肉成分可以通过反馈来修改 仅当学习了发声时，才会出现外围； 2）这个感官 反馈来自机械感受器、本体感受器或热感受器 声道或呼吸系统，并且听觉反馈不是 必要的; 3）扰动后的补偿性运动反应 呼吸压力首先出现在歌曲学习的塑性阶段 在将输出与模型音节匹配的过程中； 4）那个 呼吸和发声器官运动神经元接收来自共同前运动神经元的输入 来源; 5）为了实现声音的复杂性，鹦鹉依赖于增加 呼吸和颅颌运动模式的可塑性可以抵消 更简单的气管注射管带来的限制。
