Recent advances in brain stimulation techniques: The interface with cognitive psychology

Abstract

There has been an increase in studies utilizing electric or magnetic brain stimulations to investigate the causal relationships between brain regions and cognitive functions. Within this paper, we review recent developments within this area, covering studies about the effects of transcranial direct current stimulation (tDCS) on working-memory enhancements, the effects of transcranial alternating current stimulation (tACS) on visual perception, and the effects of transcranial magnetic stimulation (TMS) on time perception. Finally, we discuss this new perspective and some of the possible applications of future brain stimulation techniques to cognitive psychology.
