The projections from the cortical vocal fold area were studied in five squirrel monkeys (Saimiri sciureus) with the aid of the autoradiographic tracing technique. The location of the cortical vocal fold area was determined by exploring the exposed frontal cortex with roving electrodes while examining the larynx for vocal fold adduction. The following projections were found: To the orbital cortex (area 11), dorsomedial frontal cortex (areas 6 and 8), Broca's area (area 44), lower fronto-parietal cortex (areas 6, 4, 3 and 1), fronto-parietal operculum (area 50), insula (areas 14 and 13), caudatum, putamen, claustrum nucl. reticularis th., nucl. ventralis anterior, nucl. ventralis lateralis, nucl. ventralis posteromedialis, nucl. centralis inferior, nucl. centralis lateralis, nucl. medialis dorsalis, nucl. pulvinaris medialis, griseum pontis, nucl. parabrachialis medialis and lateralis, nucl. tr. spinalis n. trigemini and nucl. tr. solitarri. A comparison of the projection system with a previous mapping study for vocalization (Jürgens and Ploog, 1970) revealed that there are two areas yielding vocalization when electrically stimulated which receive direct projections from the cortical larynx area, namely, the cortex around the anterior sulcus cinguli and the parabrachial nuclei at the pons-midbrain transition. The possible relevance of these structures for vocalization is discussed.
借助放射自显影追踪技术，对5只松鼠猴（松鼠猴属）的皮质声带区投射进行了研究。通过用游动电极探查暴露的额叶皮质，同时检查喉部声带内收情况，确定了皮质声带区的位置。发现了以下投射：至眶皮质（11区）、背内侧额叶皮质（6区和8区）、布洛卡区（44区）、额顶叶下部皮质（6区、4区、3区和1区）、额顶叶岛盖（50区）、岛叶（14区和13区）、尾状核、壳核、屏状核、丘脑网状核、腹前核、腹外侧核、腹后内侧核、下中央核、外侧中央核、背内侧核、内侧枕核、脑桥灰质、内侧和外侧臂旁核、三叉神经脊束核和孤束核。将该投射系统与先前一项发声定位研究（于尔根斯和普洛格，1970年）进行比较发现，电刺激时有两个区域会发声，它们直接接受来自皮质喉区的投射，即扣带沟前部周围的皮质和脑桥 - 中脑交界处的臂旁核。讨论了这些结构与发声可能的相关性。
