In this study, we applied repetitive transcranial magnetic stimulation (rTMS) to investigate the effects of number of pulses of rTMS on the phenomenon of perceptual reversal. It has been known that the right SPL (superior parietal lobule) has a role in perceptual reversal of the spinning wheel illusion. We measured the IRT (inter-reversal time) of perceptual reversal. We compared the effects of 1Hz 60pulses, 1Hz 120pulses and 1Hz 240pulses rTMS. The results showed that when 1Hz 60pulses of rTMS was applied over the right SPL, the IRT was significantly smaller. On the other hand, when 1Hz 240pulses of rTMS was applied over the right SPL, the IRT was significantly longer IRT. When 1Hz 120pulses of rTMS was applied over the right SPL, there were no significant differences. Moreover, to investigate whether these effects are affected by the rTMS condition with stimulus frequency, or not, we compared the effects of 0.25Hz 60pulses, 0.5Hz 60pulses, 0.25Hz 120pulses and 0.5Hz 120pulses of rTMS. When 0.25Hz 60pulses or 0.5Hz 60pulses of rTMS was applied over the right SPL, the IRT was significantly smaller. When 0.25Hz 120pulses or 0.5Hz 120pulses of rTMS was applied over the right SPL, there were no significant differences. Therefore, it was found that the IRT of perceptual reversal primarily affected by the number of pulses and doesn't affect the stimulus frequency of rTMS.
