[Objective] The influence of binocular disparity on self-motion perception was investigated by source localization of visual evoked potentials (VEPs). [Method] VEPs were recorded from 14 healthy young adults (six males and eight females, aged 21–24). Three types of visual stimuli were used: optic flow (OF), random dot stereogram with a radial gradient of disparity (RG-RDS), and their combination (RG-RDS&OF). To extract the motion-related component from RG-RDS&OF, the difference waveform was defined as the subtraction of the response for RG-RDS from one for RG-RDS&OF (S-OF). Signal sources of each stimuli and the S-OF were estimated by sLORETA. [Result] N190 latency for RG-RDS&OF was significantly longer than for RG-RDS. At latencies ranging from 200 to 240 ms, the OF showed activity in the cuneus and in the precuneus. On the other hand, S-OF indicated activity in the cuneus, precuneus, superior frontal gyrus, precentral gyrus, and postcentral gyrus. [Discussion] The results of RG-RDS&OF and RG-RDS suggested that RG-RDS&OF may delay activity related to binocular disparity. The OF and the difference waveform results showed similar trends compared to previous studies on self-motion perception. The results of RG-RDS&OF and OF suggested that information processing related to self-motion perception were more active in RG-RDS&OF than in OF.

Patterned rTMS is becoming popular for its ability to induce strong LTP/LTD-like changes. Theta burst stimulation (TBS) and quadripulse stimulation (QPS) are representative stimulation methods. TBS is becoming increasingly popular as a stimulus suitable for research and clinical applications due to its short stimulus duration. QPS is a stimulation method developed in Japan in which monophasic TMS is given every 5 seconds for 30 minutes with 4 shots. QPS is characterized by low interindividual variability in efficacy, and case reports have emerged regarding its use as an intervention for post-stroke motor paralysis. It is expected to be applied to patients with diseases in the future.
