This paper describes a series of experiments directed toward the following questions: a) do signals from musculotendinous receptors reach consciousness?, and b) does feed-forward information of muscular force and expected extent of voluntary movement exist? To answer these questions, data from voluntary compression of springs and strain-gauge have been analyzed in healthy young subjects. By successive elimination of information from other sources, it was possible to verify that receptors in muscles and tendons do signal movement magnitude and muscular tension to the cerebral cortex, and that this information does reach consciousness. There also exists a feed-forward mechanism signalling parameters of voluntary contraction. However, it is unclear whether peripheral, subcortical or intracortical loops are directly involved.
a) 来自肌腱受体的信号能否传达到意识层面？以及b) 是否存在肌肉力量和预期的自主运动范围的前馈信息？为了回答这些问题，对健康年轻受试者在自愿压缩弹簧和使用应变仪时的数据进行了分析。通过逐步排除来自其他来源的信息，得以证实肌肉和肌腱中的受体确实会向大脑皮层发送运动幅度和肌肉张力的信号，并且这些信息确实能传达到意识层面。还存在一种前馈机制，可发出自主收缩参数的信号。然而，尚不清楚外周、皮层下或皮层内环路是否直接参与其中。
