Projections from the cerebellar nuclei (CN) and the internal segment of the globus pallidus (GPi) to areas 6 and 4 via the thalamus were examined electrophysiologically in monkeys. In addition to the well-known pallido-thalamo-cortical projection to area 6, some thalamic neurons with CN input were found to project to area 6. Seventeen neurons in VLc, area X and the dorsal margin of VPLo were activated antidromically by stimulation of supplementary motor or premotor areas, and orthodromically by CN stimulation. Twelve neurons in area X and the medial part of VPLo were found to receive CN input and to project to the arcuate premotor area (APA). Four neurons in the VLo-X border region which were identified to project to APA were inhibited by GPi stimulation.
通过电生理学方法在猴子身上研究了小脑核（CN）和苍白球内侧段（GPi）经丘脑向6区和4区的投射。除了众所周知的苍白球-丘脑-皮质向6区的投射外，还发现一些接受CN输入的丘脑神经元投射到6区。刺激辅助运动区或运动前区可逆向激活VLc、X区和VPLo背侧边缘的17个神经元，刺激CN可顺向激活这些神经元。发现X区和VPLo内侧部分的12个神经元接受CN输入并投射到弓状运动前区（APA）。确定投射到APA的VLo-X边界区域的4个神经元受到GPi刺激的抑制。
