The extent of the region of the diaphragm around the esophagus that displays greatly reduced activity during the expulsive phase of vomiting was determined from electromyographic studies in cats to be about 0.75-1.0 cm from the esophagus. Horseradish peroxidase injected into this region retrogradely labeled motoneurons throughout most of the rostral-caudal extent of the phrenic nucleus, with the exception of caudal C6 and rostral C7. This widespread intermingling of motoneurons that innervate the region of reduced activity with other phrenic motoneurons creates a difficulty for needed follow-up studies of diaphragmatic control during vomiting.
通过对猫的肌电图研究确定，在呕吐的排出阶段活动显著降低的食管周围膈肌区域，其范围是距离食管约0.75 - 1.0厘米。向该区域注射辣根过氧化物酶后，逆向标记了整个膈神经核大部分头尾范围内的运动神经元，但尾侧C6和头侧C7除外。支配活动降低区域的运动神经元与其他膈神经运动神经元广泛混合，这给呕吐期间膈肌控制所需的后续研究带来了困难。
