| Research Abstract |
In order to evaluate the higher brain function related to the circular vection (CV), cortical hemodynamic responses to optokinetic (OK) stimulation detected by multichannel near infrared spectroscopy (NIRS) system were measured in the healthy subjects. OK stimulation in horizontal direction presented increase of hemodynamic response in the vestibular related brain areas, but decrease in the visual related brain areas. Directional changes of OK stimulation between horizontal and vertical axes showed some differences in the hemodynamic responses within the vestibular related brain areas.
