Abstract : Use-dependent plasticity (UDP) is an important neural basis of functional recovery by repetitive training. By repeating a motor task, we can perform it faster and more correctly. After finishing the training, the corresponding performance improvement is maintained for a certain period. This is because the motor neuronal network related to the trained movement is now reformed and reinforced in a more efficient way. Changes of this nerve network take place in both excitability and inhibitory pathways due to neural plasticity, such as a continuous change of the synaptic transmission efficiency, i.e., long-term potentiation and long-term depression. In order to increase the effectiveness of motor training, it is necessary to explore in more detail precisely how the motor neuronal network related to UDP works. By the artificial induction of neural plasticity using repetitive electric or magnetic stimulation, the actions of living things can be changed. This approach has increased the possibility of medical treatment. Although various stimulation devices have now been introduced into clinical rehabilitation, repetitive training is still a key fundamental approach. It is important to determine the mechanism that works when UDP is induced and modulated, resulting in functional recovery.
