We clarified that the superior parietal lobule (SPL) in the right hemisphere involves the perceptual reversal of an ambiguous figure using repetitive transcranial magnetic stimulation (rTMS). The aim of this study was to investigate what effect the stimulus frequency and number of pulses of rTMS had on the Inter-reversal time (IRT) of perceptual reversal on the right SPL. Spinning wheel illusions were used as the ambiguous figures for stimulation in this study. To investigate what effect rTMS had over the right SPL during perceptual reversal, a 0.25 Hz 60-pulse, a 0.25Hz 120-pulse, a 0.5Hz 120-pulse and a 1Hz 120-pulse biphasic rTMS at 90% of the resting motor threshold was applied over the right SPL and right posterior temporal lobe (PTL), respectively. As a control, a no-TMS trial was also conducted. We found that the 60-pulse rTMS at 0.25Hz applied over the right SPL caused shorter IRT. However, there was no significant difference in the 120-pulse rTMS at 0.25Hz, 0.5Hz and 1Hz applied over the right SPL. Moreover, we compared this study to a previous study. Therefore, the application of rTMS over the right SPL suggested that the IRT of perceptual reversal was changed by rTMS conditions such as the number of pulses.
