hodal stimulation can decrease the excitability of the motor (Nitsche and Paulus 2000; Liebetanz et al. 2002; Nitschc, Nitsche et al 2003), visual (Antal et al. 20)1. 2004) and somatosensory convex (Dlcckh&cr et al. 2(06). In the first experiment, the cathodal electrode was placed over FP2 and the anodal

ion size, N. They are shown in Antal et al 2009c. In this paper we analyze the same questions but for games with mixed strategies. By analogy with Antal et al. 2009c, we use global mutation rates. Hence, if a mutation occurs, then a mixed strategy is chosen at random from a uniform distribution over the E
