This study used bilateral transcranial direct current stimulation (tDCS) to target neural generators of auditory Mismatch Negativity (MMN) and oddball P300 in schizophrenia patients. tDCS was applied to the pre-frontal cortex in a parallel between-group design. There was a significant main effect of stimulation resulting in modulation of MMN amplitude. This effect was mainly driven by a non-significant, but large, effect-size decrease in MMN amplitude with anodal stimulation. This is the first study to demonstrate that tDCS is able to engage and modulate an EEG-based auditory processing measure in schizophrenia. Published by Elsevier B.V.
