The functions of the cortical and subcortical motor areas have been regarded as the execution and control of limb movements. We introduce recent neuroimaging evidence in humans that somatic sensation elicited by afferent inputs that signal limb movement also engage the motor areas. It is generally understood that somatic sensation can only be experienced once movement has been executed. Here we provide evidence that somatic sensation of limb movement can be internally simulated before the movement gets started by recruiting the motor areas. It is suggested that the sensory experiences that are expected when movements are actually executed can be internally simulated in the network of the motor areas during motor imagery.
皮质和皮质下运动区域的功能一直被认为是肢体运动的执行和控制。我们介绍了近期在人类中的神经影像学证据，即由发出肢体运动信号的传入输入所引发的躯体感觉也会涉及运动区域。人们通常认为，只有在运动执行之后才能体验到躯体感觉。在此我们提供证据表明，通过激活运动区域，在运动开始之前就可以对肢体运动的躯体感觉进行内部模拟。有人提出，在运动想象过程中，运动区域网络可以对实际执行运动时预期的感觉体验进行内部模拟。
