It is unclear whether peripheral, subcortical or intracortical loops are directly involved between receptors in muscles and tendons and the cerebral cortex in signaling movement magnitude and muscular tension information. Previous experiments have indicated that this information does reach consciousness. Data from voluntary compression of springs and strain-gauge were analyzed in patients with unilateral focal lesions of the cerebral hemispheres. It was found that the perception of signals of muscular tension is abolished by lesions of the contralateral cortex near the central sulcus. It was concluded that the possibility exists of separate cortical projection areas for kinesthetic signals from muscles and from joints.
目前尚不清楚外周、皮层下或皮层内环路是否直接参与肌肉和肌腱中的感受器与大脑皮层之间传递运动幅度和肌肉张力信息的过程。先前的实验表明，这些信息确实能到达意识层面。对大脑半球单侧局灶性病变患者进行了自愿压缩弹簧和应变仪数据的分析。结果发现，中央沟附近对侧皮层的病变会消除对肌肉张力信号的感知。得出的结论是，存在来自肌肉和关节的动觉信号的独立皮层投射区域的可能性。
