Our findings revealed the nucleus ventralis lateralis pars oralis (VLo) projection to motor area, and the nucleus ventralis anterior pars principalis (VApc) projections to the premotor and supplementary motor areas (SMA). The VLo gave rise to thalamocortical projections terminating in the superficial half of layer I, mainly in the forelimb motor area. The VApc gave rise to the superficial projections to the post-arcuate premotor area around the arcuate genu and arcuate spur as well as SMA. We suggested that the medial pallidal segment projects to the motor area via VLo, and to the premotor area and SMA via VApc. We also proposed that the premotor area and SMA receive cerebellar afferents via nucleus ventralis lateralis pars caudalis and area X.
我们的研究结果揭示了腹外侧核嘴侧部（VLo）向运动区的投射，以及腹前核主部（VApc）向运动前区和辅助运动区（SMA）的投射。VLo发出丘脑皮质投射，终止于I层的浅层，主要在 forelimb 运动区。VApc发出浅层投射至围绕弓状膝和弓状棘的弓状后运动前区以及SMA。我们认为内侧苍白球段通过VLo投射至运动区，并通过VApc投射至运动前区和SMA。我们还提出，运动前区和SMA通过腹外侧核尾侧部和X区接受小脑传入纤维。
