下行的皮层和皮层下通路通向脊髓，构成了大脑控制脊髓运动机制的主要途径。这里提出的两项研究试图阐明这些通路在控制自由运动的猴子的运动中的作用。这些研究是由脊髓灰质皮层和皮层下通路末端分布差异的解剖学发现推动的（图1）。主要来自中央前回和后回的皮质脊髓纤维分布到背角固有核、整个内部区和外侧运动神经元（Kuypers, 1960； Liu和Chambers， 1964）。通往固有核的纤维主要来自中枢后回，而通往运动神经元和内部区的纤维主要来自中央前回。后一种纤维大部分在对侧终止，但有些在同侧终止。皮质脊髓下通路分为内侧和外侧系统
THE descending cortical and subcortical pathways to the spinal cord constitute the main routes by which the brain can govern the spinal motor mechanisms. The two studies presented here attempt to elucidate the role of these pathways in the control of movements in the freely-moving monkey.These studies were prompted by the anatomical findings with respect to the differential terminal distribution of the cortical and subcortical pathways in the spinal grey matter (Figure 1). The corticospinal fibres which arise primarily from the pre-and post-central gyrus are distributed to the nucleus proprius of the dorsal horn, throughout the internuncial zone and to the lateral motoneurons (Kuypers, 1960; Liu and Chambers, 1964). The fibres to the nucleus proprius arise primarily from the post-central gyrus while those to the motoneurons and the internuncial zone arise primarily from the precentral gyrus. The bulk of the latter fibres terminate contralaterally but some terminate ipsilaterally. The subcorticospinal pathways have been grouped into medial and lateral systems based upon
