Background and Objectives The study is to investigate if left or right dorsolateral prefrontal cortex is important in modulating the craving to drug related cues. Methods The present investigation examined different combinations between left/right and high/low frequency rTMS on cue induced craving to methamphetamine, with active sham rTMS on P3 region on a total of 50 subjects. Results The results showed that either at left or right side, both high and low frequency rTMS are effective in decreasing the cue induced craving to methamphetamine. Discussion and Conclusions In conclusion, bilateral frontal hemispheres are effective in modulating the cue induced craving to methamphetamine with rTMS. Scientific Significance TMS targeting prefrontal cortex is effective for craving modulation; however the mechanism is more than potentiation or depression of single brain region.
