case_images: T1-weighted MRI was used to simulate electrical field distribution using SimNIBS v4.0 (http://www.simnibs.org/), and montages were finalized to deliver 0.5 mA anodal retuning direct current at TP9, P5, PO3, and O9 to achieve a peak electric field of 0.195823 V/m over the left LOC (Fig. 1A). The respective target scalp location was identified using the Brainsight  neuronavigational system (https://www.rogue-research.com/tms/brainsight-tms/). A significant improvement (> 25% reduction) in AVH (using the AH rating scale) and AVAs was reported (Fig. 1B) with "much improved" rating on the clinical global impression scale.
