Representation of the masticatory muscles within the motor trigeminal nucleus was studied in rats by the horseradish peroxidase (HRP) method and the antidromic field potential method. The motor trigeminal nucleus of the rat could be divided cytoarchitecturally into a dorsolateral and a ventromedial division. Within the dorsolateral division, the temporal muscle was represented dorsomedially, the masseter muscle dorsolaterally and laterally, and the lateral and medial pterygoid muscles ventrolaterally. Within the ventromedial division, the anterior digastric muscle was represented dorsomedially and the mylohyoid muscle ventrolaterally. Distribution of antidromic field potentials evoked by stimulation of the mylohyoid and masseteric nerves coincided with the results from the HRP investigation.
采用辣根过氧化物酶（HRP）法和逆向场电位法，在大鼠中研究了咀嚼肌在三叉神经运动核内的代表区。大鼠的三叉神经运动核在细胞结构上可分为背外侧部和腹内侧部。在背外侧部，颞肌代表区位于背内侧，咬肌代表区位于背外侧和外侧，翼外肌和翼内肌代表区位于腹外侧。在腹内侧部，二腹肌前腹代表区位于背内侧，下颌舌骨肌代表区位于腹外侧。刺激下颌舌骨肌神经和咬肌神经所诱发的逆向场电位分布与HRP研究结果一致。
