The rTMS effect on perceptual reversal of ambiguous figures.
Past research about perceptual reversal of ambiguous figures indicate that the superior parietal lobule is involved in perceptual reversal. To investigate the rTMS effect over right superior parietal lobule on perceptual reversal, three trials were performed. In Trial 1, rTMS was applied over the right superior parietal lobule. In Trial 2, rTMS was applied over the right posterior temporal lobe. In Trial 3, no TMS was applied over the subject's skull. The inter-reversal time of perceptual reversal between these three trials were compared. It was suggested that the right superior parietal lobule plays a critical role in perceptual reversal of ambiguous figures. Furthermore, short-duration and long-duration rTMS were conducted in the present study, respectively. The rTMS duration effects on perceptual reversal were also compared.
