重复刺激大鼠杏仁中央核（CAm）诱导有节律的咀嚼运动或连续的下颌打开。这两种类型的下颌运动伴随着巧合的活动，下颌舌骨（Myl）神经。检查CAm刺激对双侧Myl和咬肌（Mass）神经或其运动神经元（分别为Myl-Dig [二腹肌]和Mass）活动的影响。CAm刺激诱导对侧显性促进Myl神经活动以及Myl-Dig运动神经元。这些易化效应是由Myl-Dig运动神经元中的兴奋性突触后电位（EPSP）引起的。的群众运动神经元，三分之一的抑制或超极化对侧CAm刺激，而少数人促进和大多数不受影响。
Repetitive stimulation of the rat central amygdaloid (CAm) nucleus induced rhythmic masticatory jaw movements or continuous jaw opening. Both types of jaw movements were accompanied by coincidental activities of the mylohyoid (Myl) nerve. The effects of CAm stimulation were examined on activities of bilateral Myl and masseteric (Mass) nerves or their motoneurons (Myl-Dig [digastric] and Mass, respectively). CAm stimulation induced contralaterally dominant facilitation of the Myl nerve activity as well as Myl-Dig motoneurons. These facilitatory effects were caused by EPSP [excitatory postsynaptic potential] seen in Myl-Dig motoneurons. Of the Mass motoneurons, a third were inhibited or hyperpolarized by contralateral CAm stimulation, while a few were facilitated and the majority unaffected.
