Motor behaviour is most efficiently controlled by correcting only disturbances that influence task success. It is currently thought that such control is computed within a transcortical feedback pathway. Here we show that, for postural hand control, even the fastest spinal feedback pathway can produce efficient corrective responses, forcing a re-evaluation of how the nervous system derives the control laws that support motor behavior.
运动行为主要通过仅纠正影响任务成功的干扰来进行最有效的控制。目前认为，这种控制是在皮质下反馈通路内计算的。在这里，我们表明，对于姿势手控制，即使是最快的脊髓反馈通路也可以产生有效的纠正反应，这迫使我们重新评估神经系统如何推导出支持运动行为的控制律。
