The concept of primitives has been used in motor control both as a theoretical construct and as a means of describing the results of experimental studies involving multiple moving elements. This concept is close to Bernstein's notion of engrams and level of synergies. Performance primitives have been explored in spaces of peripheral variables but interpreted in terms of neural control primitives. Performance primitives reflect a variety of mechanisms ranging from body mechanics to spinal mechanisms and to supraspinal circuitry. This review suggests that primitives originate at the task level as preferred time functions of spatial referent coordinates or at mappings from higher level referent coordinates to lower level, frequently abundant, referent coordinate sets. Different patterns of performance primitives can emerge depending, in particular, on the external force field.

关于电机控制中的基元。

原语的概念已在电动机控制中用作理论构造和描述涉及多个运动元素的实验研究结果的手段。这个概念与伯恩斯坦的信物概念和协同作用水平很接近。在外围变量的空间中已经探索了性能原语，但是根据神经控制原语对其进行了解释。表演原语反映了多种机制，从人体力学到脊柱机制再到棘上神经回路。这项审查表明，图元起源于任务级别，是空间参考坐标的首选时间函数，或者起源于从较高级别的参考坐标到较低级别（经常是丰富的）参考坐标集的映射。可能会出现不同类型的性能原语，
