| Abstract(in English) | We investigated whether a visually induced illusory self-motion sensation (circularvection (cv)) would induce a recalibration of a saccade. A round curtain with vertical stripes was rotated at 50 deg/sec around a subject a seated on a stationaty chair. Five light-emitting diodes (LEDs) mounted at 5-degree intervals were located in front of the subject. First, the subject's perception of circularvection, usually occurring within 20 sec from the start of the curtain's motion, was confirmed. Next, the light inside the curtain went off and he was asked to fix gaze on the center LED and then make a saccade to a randomly chosen, briefly (100 msec). Flashed LED among the four remaining LEDs inside the rotating curtain. As a control task, the same subject was exposed visually to a rotating curtain for 2 sec under illumination and then made a saccade from the center LED to one of the four peripheral LEDs flashed briefly under nonillumination. Eye movement was measured by an electro-oculogram. The amplitude and the landing position of saccades to a flashed target became hypometric when the saccades were made in the inverse direction to the CV. Saccades in the same direction as the CV were normometric. Circularvection seems to be involved in the decision process of a saccade amplitude as well as the sensation of self-motion. |
