Transcranial direct current stimulation (tDCS) has been reported to ameliorate auditory hallucinations that are nonresponsive/minimally responsive to antipsychotic treatment in schizophrenia. The neurobiological basis of the tDCS effects in ameliorating auditory hallucinations is yet to be explored. In this case report, for the first time, using the novel method for noninvasive assessment of cortical plasticity, we demonstrate potential neuroplasticity effect of tDCS in improving treatment-resistant auditory hallucinations in a schizophrenic patient.
