Because considerable work has implicated the basal ganglia in oral-ingestive behavior, an assessment was made of the effects of trigeminal stimuli upon entopeduncular single units. Units wre recorded extracellularly in awake, paralyzed and locally anesthetized cats. The effects of two types of sensory input were tested. Afferents from periodontal mechano-receptors involved in reflex jaw opening were stimulated via electrodes in the inferior dental nerve. Afferents from stretch receptors involved in reflex jaw closure were stimulated via electrodes in the trigeminal mesencephalic nucleus. A significant proportion of cells responded to both types of stimulation. The data were discussed in the context of a basal ganglionic role in oropharyngeal motor processes and a more general role in movement per se.
由于大量研究表明基底神经节与口腔摄食行为有关，因此对三叉神经刺激对视丘内单个神经元的影响进行了评估。在清醒、瘫痪并局部麻醉的猫身上，细胞外记录神经元活动。测试了两种感觉输入的影响。通过下牙槽神经中的电极刺激参与反射性张口的牙周机械感受器传入神经。通过三叉神经中脑核中的电极刺激参与反射性闭口的牵张感受器传入神经。相当一部分细胞对两种类型的刺激都有反应。这些数据在基底神经节在口咽运动过程中的作用以及在运动本身中更普遍的作用的背景下进行了讨论。
