Abstract
Finite element method (FEM) based models derived from magnetic resonance imaging (MRI) have become ubiquitous tools for estimating transcranial direct current stimulation (tDCS) effects [1,2]. With increasingly available free toolboxes, researchers can quickly examine the electrical current distribution that mimics the actual setting of tDCS clinical studies. Model estimates are then used to compute current dose in the brain and often correlate to behavioral or functional changes associated with prescribed stimulation [3].
