Exploring motor and force control in human multi-joint movements

在视觉引导的到达运动中，大脑在视觉空间中制定运动计划，然后计算肌肉活动模式以实现运动。本研究建立了感觉运动转换过程的神经网络模型，提供了一个发现，深入了解运动皮层细胞活动的基本性质，并证明我们的大脑实际上具有冗余的性质，使得物理上相同的运动可以由两个不同的运动规划过程执行。这意味着残疾的运动功能可以通过引发完整的转化过程来恢复。

In visually-guided reaching movements, the brain makes a movement plan in visual space and then computes muscle activity pattern to achieve the movement. Building a neural network model for the sensorimotor transformation process, the present study provided a finding that gains insight into the fundamental property of motor cortical cell activities and demonstrated that our brain actually have a redundant nature such that a physically identical movement can be executed by two distinct motor planning processes. This implies that disabled motor function can be restored by eliciting the intact transformation process.
