The organization of the motor cortex was reinvestigated with intracortical microstimulation, in light-anaesthetized (ketamine) rats. A posterolateral (PL) vibrissae area was found in addition to the rostral one, and blinks of the contralateral eyelids were elicited from a part of this PL area. Several cortical representations such as neck or tail were largely overlapping with neighbouring areas. Vegetative effects (mainly myosis and swallowing) were obtained from a medial cortical strip. Within the PL vibrissae area, a topical arrangement related to the vibrissal rows was observed, whereas in the leg areas, no individual representation of muscles could be evidenced. These results are compared with the maps previously published, and discussed in terms of specificity, musculotopy and overlapping of motor areas.
在轻度麻醉（氯胺酮）的大鼠中，通过皮层内微刺激对运动皮层的组织进行了重新研究。除了吻侧的触须区域外，还发现了一个后外侧（PL）触须区域，并且从该PL区域的一部分引发了对侧眼睑的眨眼。诸如颈部或尾部等几种皮层表征与相邻区域有很大重叠。在内侧皮层条带可获得自主效应（主要是瞳孔缩小和吞咽）。在PL触须区域内，观察到与触须排相关的局部排列，而在腿部区域，无法证明肌肉有单独的表征。将这些结果与先前发表的图谱进行了比较，并从运动区域的特异性、肌肉定位和重叠方面进行了讨论。
