The transcranial stimulation with direct currents (tdcs): An historical and conceptual minireview

Abstract

Transcranial Stimulation with Direct Currents (tDCS) is a method for non invasive brain stimulation created to induce functional changes in cerebral cortex. tDCS consists of application on the scalp of electrodes providing a low intensity direct current influencing neuronal functions. tDCS is not the only neurostimulation method for neuroscience clinical practice and research and can be used for treat many different clinical conditions such as migraine prevention, autism spectrum disorders (ASD), cerebral palsy rehabilitation, post-traumatic brain injury neuropsychological disorders.
