Transcranial direct current stimulation (tDCS) is a non-invasive method to modulate brain activity. Its effects are attracting enormous interest as a therapeutic tool for motor rehabilitation. Motor learning can be defined as the ability to perform a task motor providing a relatively permanent improvement in performance thereof. This research aimed to investigate the effects of tDCS on M1 in the process of motor learning in healthy adult females. For this purpose 21 subjects performed two types of motor tasks, TJJ and Maze test and tDCS on primary motor cortex. The results indicated a significant improvement of motor performance after stimulation of the anodic to the primary motor cortex TJJ (p <0.000001) and cathodic tDCS in primary motor cortex showed hinder performance (p = 0.006). To the maze test was not significant effect of tDCS for the periods of acquisition, transfer, retention, and visual retention. At the end our results show that tDCS anode and cathode in primary motor cortex influences motor performance, confirming the idea of tDCS associated with motor function.
