The cortical projection areas of thalamic neurons with basal ganglia and/or cerebellar inputs were studied electrophysiologically in unanesthetized monkeys. Thalamic neurons which receive inhibition from the pallidum were found to project to the motor cortex (area 4) as well as to premotor cortex. The neurons with pallidal input and motor cortical projection were located mainly in VLo. This result indicates that the basal ganglia innervate the motor cortex through the thalamus. Thus the basal ganglia can modify the cortical output for controlling movements directly through this pathway as compared with its influence through the prefrontal and premotor cortices.
在未麻醉的猴子身上，用电生理学方法研究了具有基底神经节和/或小脑输入的丘脑神经元的皮质投射区域。发现接受苍白球抑制的丘脑神经元投射到运动皮层（4区）以及运动前皮层。具有苍白球输入和运动皮层投射的神经元主要位于腹外侧核（VLo）。这一结果表明，基底神经节通过丘脑支配运动皮层。因此，与通过前额叶和运动前皮层的影响相比，基底神经节可通过该通路直接调节皮质输出以控制运动。
