Transcranial direct current stimulation (tDCS) modulates cerebral energy and cortical inhibition. In this study we investigated long-term effects of anodal stimulation on inhibitory neurotransmitter and energy phosphate concentration using proton and phosphorous magnetic resonance spectroscopy. Our results indicate immediate GABA reduction following anodal tDCS and further maintaining the decreased state until the end of the experiment. ATP/Pi and PCr/Pi show initial reduction following anodal tDCS and further sign of recovery by the end of the experiment.
