Abstract

Transcranial direct current stimulation (tDCS) may be able to affect language functions, over both shorter (minutes) and longer (hours to perhaps months) intervals. Individual differences in psychological capacities, neurophysiology, and neuroanatomy make within-subjects, repeated-measures designs ideal for tDCS studies using present-day methods. True 'sham' stimulation may not be possible at higher levels of current. Designs that take these factors into account, coupled with improved methods of focusing current and orchestrating when and where it is applied, will likely strengthen the usefulness of tDCS for investigating language functions and improving them.
