Stimulation of the supratrigeminal area (STA) of the rat induced a monosynaptic EPSP in most mylohyoid-digastric motoneurons and a monosynaptic IPSP or EPSP in the majority of masseteric ones, contralaterally. Stimulation of the central amygdaloid nucleus induced the ipsilateral STA activity immediately followed by the contralateral mylohyoid nerve activities. The same amygdaloid stimulated excited 19 of 46 STA neurons, which were antidromically identified to project to the contralateral trigeminal motor nucleus. Nine of these were monosynaptically excited. The mean of the antidromic and monosynaptic latencies of these neurons explains the mean onset latencies of the amygdaloid influences on the contralateral trigeminal motoneurons. Therefore, the shortest crossing amygdalo-motoneuronal pathway is probably disynaptic and mediated by commissural STA neurons.
刺激大鼠的三叉上区（STA），在大多数下颌舌骨肌-二腹肌运动神经元中诱发单突触兴奋性突触后电位（EPSP），而在大多数咬肌运动神经元中，对侧诱发单突触抑制性突触后电位（IPSP）或EPSP。刺激中央杏仁核立即诱发同侧STA活动，随后是对侧下颌舌骨神经活动。同样刺激杏仁核，兴奋了46个STA神经元中的19个，经逆向鉴定它们投射到对侧三叉神经运动核。其中9个被单突触兴奋。这些神经元的逆向和单突触潜伏期平均值解释了杏仁核对侧三叉运动神经元影响的平均起始潜伏期。因此，最短的杏仁核-运动神经元交叉通路可能是双突触的，并由连合STA神经元介导。
