在计算研究的基础上，已经提出，中枢神经系统内部模拟了运动系统在计划，控制，酸学习方面的动态行为。这种内部模型的存在和使用仍在争论中。研究了一项感觉运动集成任务，其中参与者估计了他们的一只手的位置，在黑暗和外部强加的力下进行的运动结束时。在最佳状态估计的理论框架内分析了此任务中错误的时间传播。这些结果为存在内部模型的存在提供了直接的支持。
On the basis of computational studies it has been proposed that the central nervous system internally simulates the dynamic behavior of the motor system in planning, control, acid learning; the existence and use of such an internal model is still under debate. A sensorimotor integration task was investigated in which participants estimated the location of one of their hands at the end of movements made in the dark and under externally imposed forces. The temporal propagation of errors in this task was analyzed within the theoretical framework of optimal state estimation. These results provide direct support for the existence of an internal model.
