大鼠的第一运动（MI）皮层被确定为最低强度的电刺激可以诱发运动的区域。这个区域的位置与额叶和顶叶皮层的细胞结构相关。在Nissl染色切片中可以辨别出两个前部区域：内侧无颗粒区，由浅染色层III和致密层II标记，以及外侧无颗粒区，其具有更均匀的浅层和包含大的、密集染色细胞的宽层V。这两个区域都投射到脊髓，因此可以包括在躯体感觉运动皮层中。大鼠的MI与外侧无颗粒区一致，但也与第一躯体感觉（SI）代表的相邻颗粒皮质的一部分重叠。大鼠MI皮质可以通过微刺激技术和大鼠的细胞结构来识别。
The 1st motor (MI) cortex of the rat was identified as the region from which movements could be evoked by the lowest intensity of electrical stimulation. The location of this region was correlated with cytoarchitecture in the frontal and parietal cortex. Two frontal areas can be discerned in Nissl-stained sections: the medial agranular field, marked by a pale-staining layer III and a compact layer II, and the lateral agranular field, which has more homogeneous superficial layers and a broad layer V containing large, densely staining cells. Both of these regions project to the spinal cord and can therefore be included in the somatic sensorimotor cortex. MI in the rat coincides with the lateral agranular field but also overlaps with part of the adjacent granular cortex of the 1st somatic sensory (SI) representation. The rat MI cortex can be identified by microstimulation techniques and by cytoarchitecture in the rat.
