| Abstract(in English) | Humans acquire a variety of motor skills autonomously interacting with environments from infancy. Motor skills are learned through practice, and the motor commands and the sensory feedback that resulted from the practice are stored in the brain. While undertaking tasks related to handling objects, we have to control motor commands corresponding not only to limb properties but also object properties. The motor control mechanism that CNS uses when we interact with environments could compose the computational mechanism of perception. Here, we focus on load-on task, and clarify the goal of learning motor skills and the way we control impedance. We measure hand trajectory and surface electromyography(EMG) to estimate time-varying stiffness and torque pattern with a joint space. Our results show that the goal of learning motor skills under load-on task is to maintain the hand position and that humans produce force with co-contraction and increase stiffness level according to the weight of the object. Finally, we examined whether stiffness is an effective parameter as an efferent signal for weight perception. And here we found that stiffness represents our strategy and takes an important role in weight perception. |
