Single neuron activities of the globus pallidus were recorded in awake monkeys. Electrical stimulation of various cortical areas (the prefrontal, premotor, supplementary motor and arcuate premotor areas, and the motor cortex) inhibited spontaneous discharge of pallidal neurons. This inhibitory response was considered to be mediated through the striatum. Considerable number of pallidal neurons responded to the stimulation of more than one cortical areas. However, the neurons receiving inputs from the motor cortex and/or arcuate premotor area and those receiving inputs from the prefrontal, premotor and/or supplementary motor areas were segregated. The former neurons were located ventrolaterally in the caudal part of the globus pallidus, while the latter ones were located dorsomedially in the rostral part of the globus pallidus.
在清醒的猴子身上记录苍白球的单个神经元活动。对不同皮质区域（前额叶、运动前区、辅助运动区、弓状运动前区和运动皮质）进行电刺激会抑制苍白球神经元的自发放电。这种抑制反应被认为是通过纹状体介导的。相当数量的苍白球神经元对不止一个皮质区域的刺激有反应。然而，接受运动皮质和/或弓状运动前区输入的神经元与接受前额叶、运动前区和/或辅助运动区输入的神经元是分开的。前者位于苍白球尾部的腹外侧，而后者位于苍白球头部的背内侧。
