发声是一种复杂的行为模式，其中涉及几个皮质和皮质下结构，以产生适当的声音输出。虽然学习的发声模式，如语音，是由复杂的皮质网络产生的，但大多数哺乳动物发声所属的基因预编程发声是由脑干中的复杂神经网络产生的。该网络涉及中脑导水管周围灰质、臂旁腹外侧区、疑核后核和桥脑外侧，以及延髓外侧网状结构和尾侧网状结构。这个网络可以直接连接到控制发声的喉、呼吸和发音部分的所有运动神经元池。它通过孤束核和三叉神经脊束核接受来自喉、肺和口腔机械感受器的本体感觉反馈信息。该网络通过中脑导水管周围灰质接受来自情绪、动机和感觉结构的便利输入，该灰质是发声的整合中心和触发结构。
Vocalization is a complex behavioral pattern in which several cortical and subcortical structures are involved to produce proper vocal output. While learned vocal patterns, such as speech, are produced by a complex cortical network, genetically preprogrammed vocalizations, to which most mammalian vocalizations belong, are generated by a complex neuronal network in the brainstem. Structures involved in this network are the periaqueductal gray, ventrolateral parabrachial area, nucleus retroambiguus and the lateral pontine, as well as the lateral and caudal medullary reticular formation. This network has direct access to all motoneuron pools controlling laryngeal, respiratory and articulatory components of vocalization. It receives proprioceptive feedback information from laryngeal, pulmonary and oral mechanoreceptors via the solitary tract nucleus and spinal trigeminal nucleus. The network receives facilitating input from emotional, motivational and sensory structures via the periaqueductal gray, which serves as an integration center and triggering structure for vocalization.
