| Research Abstract |
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.
