我们的目的是确定驱动腰束腹呼气运动神经元的尾侧腹侧呼吸组（VRG）呼气(E)神经元是否对肋间神经和腰神经传入刺激有反应。结果表明，92%的上腰髓e神经元在受到肋间神经和腰神经传入神经的刺激后，其活性降低。我们得出结论，肋间和腹肌肌腱器官的传入信息对驱动腹呼气运动神经元的尾侧VRG e神经元具有抑制作用。
Our objective was to determine if caudal ventral respiratory group (VRG) expiratory (E) neurons that drive abdominal expiratory motoneurons in the lumbar cord respond to intercostal and lumbar nerve afferent stimulation. Results showed that 92% of medullary E-neurons that were antidromically activated from the upper lumbar cord reduced their activity in response to stimulation of external and internal intercostal and lumbar nerve afferents. We conclude that afferent information from intercostal and abdominal muscle tendon organs has an inhibitory effect on caudal VRG E-neurons that drive abdominal expiratory motoneurons.
