Abstract:
Transcranial direct current stimulation (tDCS) is a promising tool to improve cognitive abilities, however, a number of questions remain. When is it most effective and how does it affect the brain leading to such diverse cognitive benefits? In the following experiments we tested the extent to which tDCS modulates performance during varying levels of task load in three different visuospatial tasks. We targeted stimulation over the right parietal cortex, an area associated with spatial processing.
