The gustatory-vagal hypothesis proposes that gustatory stimulation elicits a coordinated vagal response manifested as an increase in ingestive behaviors (e.g., sucking) and a decrease in nucleus ambiguus vagal tone measured by decreases in the amplitude of respiratory sinus arrhythmia (RSA). The current study tested the gustatory-vagal hypothesis in a bottle feeding paradigm with 29 clinically stable, high-risk, low-birthweight neonates. The amplitude of respiratory sinus arrhythmia (RSA) was collected before, during, and after bottle feeding. Consistent with the gustatory-vagal hypothesis, RSA decreased during bottle feeding. In a longitudinal subsample of subjects, the pattern of RSA changes during the feeding paradigm was stable across two test sessions.
味觉-迷走神经假说提出，味觉刺激会引发一种协调性的迷走神经反应，表现为摄食行为增加（如吸吮），以及通过呼吸性窦性心律不齐（RSA）幅度降低来测量的疑核迷走神经张力下降。本研究在奶瓶喂养模式下，对29名临床状况稳定的高危低体重新生儿进行了味觉-迷走神经假说的测试。在奶瓶喂养前、期间和之后收集呼吸性窦性心律不齐（RSA）的幅度。与味觉-迷走神经假说一致，奶瓶喂养期间RSA降低。在纵向子样本中，喂食模式期间RSA的变化模式在两个测试阶段保持稳定。
