Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation that safely modulates brain activity. Several studies have shown that tDCS of the motor cortex facilitates motor learning and plasticity but there is little information on the underlying mechanisms. This analysis of metabolite changes in response to 1mA tDCS using typical PRESS and MEGA-PRESS is important in developing a complete understanding of the effects of stimulation. In this pediatric study, we did not detect the same GABA and glutamate changes in response to tDCS that have been seen in the adult literature.
