Although repetitive Transcranial Magnetic Stimulation (rTMS) is frequently used to examine emotional changes in healthy
volunteers, it remains largely unknown how rTMS is able to influence emotion.We carried out a sham-controlled single-blind
crossover study using fMRI, we examined in 20 right-handed healthy female volunteers whether a single high frequency (HF)-rTMS
session applied to the left dorsolateral prefrontal cortex (DLPFC) could influence emotional processing while focussing on blocks of
positively and negatively valenced baby faces. A single HF-rTMS session selectively influenced the processing of positively and
negatively valenced baby faces. In essence, our results indicate that the effects of one left-sided HF-rTMS sessions results in
improved processing of positive emotions and reduced negative emotional processing in never depressed female subjects
