个体化运动的能力--也就是说，独立于其他相邻身体部位的运动或姿势移动一个或多个身体部位的能力--赋予了高等哺乳动物运动系统越来越多的灵活性。行走、抓握或进食时的动作，与舞蹈、演奏乐器或说话时的动作形成了鲜明的对比。在后一种功能中使用的运动主要取决于初级运动皮层（第4区）。随着我们对运动皮层的输出组织的理解的进步（罗杰·莱蒙（Roger Lemon）最近进行了综述，这些研究主要基于对灵长类动物手部区域的研究），我们现在可以更全面地考虑单独移动身体部位所固有的某些问题，以及运动皮层可能完成这一壮举的一些方式。
The ability to individuate movements — that is, the ability to move one or more body parts independently of the movement or posture of other contiguous body parts — imparts an increasing flexibility to the motor repertoire of higher mammals. The movements used in walking, grasping, or eating contrast greatly with the phylogenetically more recent movements of the same body parts used, respectively, in dancing, playing a musical instrument, or talking. The movements used in the latter functions depend critically on the primary motor cortex (area 4). With advances in our understanding of the output organization of the motor cortex (reviewed recently by Roger Lemon1, which have been based largely on studies of the hand area in primates, we can now consider more fully certain problems inherent in moving body parts individually, and some ways in which the motor cortex might accomplish this feat.
