Abstract

In this paper, we report the results of a study on the post-intervention effects of applying anodal transcranial Direct Current Stimulation (tDCS) on the intensity of motor Event Related Desynchronization. Ten subjects were given 15 minutes of sham and 1.5 mA tDCS on two separate occasions in randomized order in a double blind setting. Post-intervention EEG was then recorded while subjects were asked to perform imagined motor imagery. Results show that the intensity of 8-13Hz Mu rhythms exhibited significant difference between the sham and tDCS groups, with an average of 24.13 μV² for sham and 32.57 μV² for tDCS with a measured t-test p value of 0.03.
