Summary

In a randomized, triple-blind, sham-controlled clinical trial, we will assess the effect of a single session frontal cortex High-Definition transcranial Direct Current Stimulation (HD-tDCS) on brain activity and functional connectivity underlying the behavioral change in attentional control in healthy participants. Participants will be recruited after meeting the inclusion criteria and will be randomly assigned to active or sham stimulation groups. All participants will undergo resting-state functional Magnetic Resonance Imaging (rsfMRI) scan and perform an Attention Network Test (ANT) in a functional Magnetic Resonance Imaging (fMRI) scanner before and after receiving a single session of active or sham HD-tDCS.
