abstract

  • Transcranial direct current stimulation (tDCS) is a technique for modulating brain function and performance on cognitive tasks through the application of a constant low current to corresponding regions of the scalp. It is noninvasive and can be repeated over time within the same subject. Therefore it represents a practical new approach in the study of mechanisms underlying cognition as well as mechanisms of neurocognitive disorders. Here we applied a 1 mA direct current and observed its effects in a critical cortical network engaged during a motor sequence task (pressing four color-coded keys according to a prompted sequence that appears on a computer screen) through an innovative process of behavioral and EEG recording with simultaneous tDCS application. As this is a visio-motor task, here we used four types of stimulation namely anodal, cathodal, visual and sham …
