Comparison of Influences on P300 Latency in the Case of Stimulating Supramarginal Gyrus and Dorsolateral Prefrontal Cortex by rTMS

The purpose of this study is to investigate influence of P300 latency in the case of stimulating SMG (Supramarginal Gyrus) and DLPFC (Dorsolateral Prefrontal Cortex). P300 of ERP (Event-Related Potentials) is induced by applying Odd-Ball task that is composed by the two sounds with different frequency. The Odd-Ball task was executed before and after magnetic stimulation by rTMS (100 stimuli with 1Hz). We compared the P300 latency before and after the rTMS magnetic stimulation. In the case of stimulating left and right SMG, P300 appeared earlier than in the case of no stimulating left and right SMG. In the case of stimulating left and right DLPFC, P300 appeared later than in the case of no stimulating left and right DLPFC.
