Research Abstract |
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.
