Comparison of cortical network effects of high-definition and conventional tDCS during visuomotor processing

tDCS is a non-invasive brain stimulation approach in which low level currents are applied across the scalp to influence underlying brain function [1–3]. The Serial Reaction Time Task (SRTT) is commonly used to investigate neural mechanisms underlying motor-learning [4]. In the SRTT, subjects make a series of button presses based upon visual location cues. When the sequence is random, mean RT remains relatively stable over time. However, when the sequence is repetitive and fixed, individuals show a progressive motor learning reflected in a reduction in reaction time (RT) across trials even if they are not told of the sequence in advance.
