The larynx serves various behaviors including vocalization and upper airway reflexes such as swallowing. It is considered that the motor output during these behaviors is controlled by pattern generating neural networks in the brainstem. In this study, the brainstem vocal sites were identified in the region between the midbrain and the medulla in guinea pigs. Swallowing-related neurons (SRNs) were identified, which has demonstrated that the SRNs exhibit various types of firing patterns during swallowing and that the SRNs form the neural network for swallowing with their complex axonal projections within the medulla.

喉提供各种行为，包括发声和上呼吸道反射，如吞咽。据认为，这些行为过程中的运动输出是由脑干中的模式生成神经网络控制的。在这项研究中，脑干发声部位被确定在中脑和髓质之间的区域在豚鼠。吞咽相关神经元（Swallowing-related neurons，SRN）的发现表明，SRN在吞咽过程中具有不同的放电模式，并与延髓内复杂的轴突投射共同构成吞咽神经网络。
