为了确定猕猴喉肌的皮层代表区，电刺激双侧半球的下外侧运动区。在α-氯醛糖麻醉下观察肌肉反应。刺激皮质表面上的区域与单极电极，由100/秒的恒定电流，导致分化收缩的甲杓，环甲或喉外肌。视觉上观察反应，并通过连接到解剖的肌肉的力传感器测量。在猕猴中，这些区域主要位于von Bonin和Bailey的组织学指定区域FCBm内。在几个实验中，心率也被监测。在阈值刺激值，心率变化只发生在主要致力于环甲肌反应的区域。本研究的结果进行了讨论，在可能的差分运动神经支配的迷走神经和副神经成分的喉返神经。
In order to determine the cortical areas of representation for the laryngeal muscles inMacaca mulatta, the inferolateral motor portions of both hemispheres were electrically stimulated. Muscular responses were observed under α-chloralose anesthesia. Stimulation of areas on the cortical surface with monopolar eletrodes, by a 100/sec constant current, resulted in differentiated contractions of the thyroarytenoid, cricothyroid or extrinsic laryngeal muscles. Responses were observed visually and measured by force transducers attached to the dissected muscles. InMacaca mulatta, these areas lie primarily within von Bonin and Bailey's histologically designated area FCBm. In several experiments, heart rate was also monitored. At threshold stimulation values, heart rate changes occurred only from the area principally devoted to responses of the cricothyroid muscle. The results of this study are discussed in relation to the possible differential motor innervation by vagal and accessory nerve components of the recurrent laryngeal nerve.
