学会发声的动物是如何协调发声和呼吸的？像斑胸草雀这样的鸣禽学习它们的歌声，从高度可变的咿呀学语开始，被称为子歌。经过几周的练习，斑胸草雀能够产生精确定时的音节和沉默模式，与呼气和吸气脉冲精确协调（Franz M, Goller F.J Neurobiol51: 129-141, 2002）。虽然成人歌曲中的呼吸被很好地描述，但相对而言，人们对亚歌曲中的呼吸模式或呼吸和声乐模式协调的过程知之甚少。为了解决这些问题，我们记录了幼斑胸草雀在它们的歌声中出现任何一致的时间或声学结构之前的胸气囊压力。我们发现亚歌包含短暂的吸气脉冲（50 ms）和较长的持续呼气压脉冲（50 - 500 ms）交替。与成人歌曲形成鲜明对比的是，呼气脉冲通常包含多个（0-8）可变时间的音节，由呼气间隙分隔，并且只有部分发声。在发育过程中，呼气脉冲变得更短，持续时间更固定，非发声部分更短，更少。这些发展变化最终导致每个呼气脉冲产生一个音节，而一个吸气脉冲填补每个间隙，形成一个类似于成人歌曲的协调序列。为了研究前脑歌曲控制核在呼吸模式发展中的作用，我们在HVC核（专有名称）病变前后进行了压力记录，发现这种操作逆转了呼吸模式测量的发展趋势。
How do animals with learned vocalizations coordinate vocal production with respiration? Songbirds such as the zebra finch learn their songs, beginning with highly variable babbling vocalizations known as subsong. After several weeks of practice, zebra finches are able to produce a precisely timed pattern of syllables and silences, precisely coordinated with expiratory and inspiratory pulses (Franz M, Goller F.J Neurobiol51: 129–141, 2002). While respiration in adult song is well described, relatively little is known about respiratory patterns in subsong or about the processes by which respiratory and vocal patterns become coordinated. To address these questions, we recorded thoracic air sac pressure in juvenile zebra finches prior to the appearance of any consistent temporal or acoustic structure in their songs. We found that subsong contains brief inspiratory pulses (50 ms) alternating with longer pulses of sustained expiratory pressure (50–500 ms). In striking contrast to adult song, expiratory pulses often contained multiple (0–8) variably timed syllables separated by expiratory gaps and were only partially vocalized. During development, expiratory pulses became shorter and more stereotyped in duration with shorter and fewer nonvocalized parts. These developmental changes eventually resulted in the production of a single syllable per expiratory pulse and a single inspiratory pulse filling each gap, forming a coordinated sequence similar to that of adult song. To examine the role of forebrain song-control nuclei in the development of respiratory patterns, we performed pressure recordings before and after lesions of nucleus HVC (proper name) and found that this manipulation reverses the developmental trends in measures of the respiratory pattern.
