Abstract:
Previous data suggest that the right temporo-parietal junction (rTPJ) may have a specific role in abnormal body perception (ABP), including out-of-body experience. We tested this hypothesis with inhibitory (1 Hz) and excitatory (15 Hz) repetitive transcranial magnetic stimulation (rTMS) of the rTPJ and a control site (CS, 5 cm posterior to the rTPJ along the lateral sulcus direction in Brodmann area 19R) in 35 healthy adults. ABP frequency was higher with 1 Hz than with 15 Hz rTMS but unaffected by the rTMS site (rTPJ/CS). Response to an own-body transformation task were delayed with 1 Hz compared to 15 Hz rTMS but also unaffected by rTMS site. ABP from rTMS at both sites induced electroencephalographic power decrease in all frequencies at left anterior and central cortical sites. Our data suggest that inhibitory rTMS can lead to ABP. However, the rTPJ may not play a specific role in this process.
