The efferent and afferent connections of the supplementary motor area (SMA) were studied in 6 squirrel monkeys using [3H]leucine and horseradish peroxidase, respectively. Efferent projections, common to all leucine-injected animals, were found to the cortical areas 9,8,44,4,2,5,7,24 and 23. Subcortically , efferents were found to the putamen, caudate nucleus, claustrum, the thalamic nuclei reticularis, ventrialis anterior, ventralis lateralis, medialis dorsalis, centralis lateralis, paracentralis , centrum medianum, parafascicularis, centralis superior lateralis, centralis inferior and lateralis posterior, the subthalamic nucleus, field H of Forel, nuel . ruber, reticular formation of midbrain, pons and medulla, the pontine gray and nucl . reticularis tegmenti pontis. Afferent connections exist with the cortical areas 9,8,6,44,4,1,2,5,7, 24 and 23, insula, fronto-parietal operculum and superior temporal sulcus. Subcortical afferent connections exist with the claustrum, nucleus of the diagonal band, nucl . basalis Meynert, basolateral amygdaloid nucleus, the thalamic nuclei ventralis anterior, ventralis lateralis, medialis dorsalis, centralis lateralis, paracentralis , centrum medianum, centralis superior lateralis, centralis inferior, lateralis posterior and pulvinaris , the posterior hypothalamus, ventral tegmental area, nucl . ruber pars parvicellularis , reticular formation of midbrain and pons, locus coeruleus and nucl . centralis superior Bechterew. The projections are discussed with respect to the possible role SMA plays in the voluntary initiation of motor actions.
分别使用[3H]亮氨酸和辣根过氧化物酶，对6只松鼠猴的辅助运动区（SMA）的传出和传入连接进行了研究。在所有注射亮氨酸的动物中，均发现有传出投射至皮质区9、8、44、4、2、5、7、24和23。在皮质下，传出纤维投射至壳核、尾状核、屏状核、丘脑网状核、腹前核、腹外侧核、背内侧核、外侧中央核、中央旁核、中央中核、束旁核、外侧上中央核、下中央核和后外侧核、底丘脑核、Forel区H、红核、中脑、脑桥和延髓的网状结构、脑桥灰质和脑桥被盖网状核。传入连接存在于皮质区9、8、6、44、4、1、2、5、7、24和23、脑岛、额顶岛盖和颞上沟。皮质下传入连接存在于屏状核、斜角带核、Meynert基底核、杏仁核基底外侧核、丘脑腹前核、腹外侧核、背内侧核、外侧中央核、中央旁核、中央中核、外侧上中央核、下中央核、后外侧核和丘脑枕、下丘脑后部、腹侧被盖区、红核小细胞部、中脑和脑桥的网状结构、蓝斑和Bechterew上中央核。文中讨论了这些投射与辅助运动区在随意运动发起中可能发挥的作用。
