几条证据表明，基底神经节在运动控制中的作用比运动本身的控制更高。首先，纹状体接收来自皮质区域的输入，这些区域有助于记忆和其他认知过程。此外，辅助运动区（通过丘脑接收苍白球输出的区域）在运动计划期间以及运动期间表现出神经元放电和代谢活动的变化。这种活动可能反映了苍白球的输入。此外，基底神经节的另一部分，黑质网状部的细胞，表现出的活动，反映了记忆，以及眼和视觉过程。最后，当刺激触发运动时，纹状体神经元会对刺激做出反应，但当对刺激的反应消失时，纹状体神经元则不会。总的来说，这些观察结果与基底神经节可能提供运动中心和皮层区域之间的界面以实现更高的大脑功能的观点一致。
Several lines of evidence suggest that the role of the basal ganglia in motor control is of a higher order than control of movements per se. First the striatum receives inputs from cortical areas that subserve mnemonic and other cognitive processes. Furthermore, the supplementary motor area (a zone that receives outputs from the globus pallidus via thalamus) exhibits changes in neuronal discharge and metabolic activity during movement planning as well as during movement. It is possible that this activity reflects its pallidal inputs. In addition, cells in another part of the basal ganglia, the pars reticulata of the substantia nigra, exhibit activity that reflects mnemonic as well as oculomotor and visual processes. Finally, there are striatal neurons that respond to stimuli when these stimuli trigger movement but not when responses to the stimuli are extinguished. Taken collectively, these observations are consistent with the view that the basal ganglia may provide an interface between motor centres and cortical areas for higher brain function.
