Three-component analysis of caloric nystagmus, focusing on horizontal, vertical, and torsional directions, using a newly developed computerized eye movement analysis system was carried out in ten normal human subjects. The caloric response was induced by cold stimulation to the right ear while the subjects were in supine and prone positions. The directions of the three components of nystagmus, were left in ten subjects (10), upward (8) or downward (2), and clockwise (10) in the supine position. In the prone position, on the other hand, the three components were directed toward the right (10), downward (5), upward (3), and counterclockwise (10) or were not present (2). These findings indicate that caloric stimulation activates the three semicircular canals simultaneously. In addition the changes in the direction of nystagmus in the supine and prone positions could not be explained in detail by the convection theory of caloric response alone.
使用新开发的计算机化眼动分析系统，对十名正常人类受试者进行了以水平、垂直和扭转方向为重点的冷热眼震三分量分析。在受试者仰卧和俯卧位时，通过对右耳进行冷刺激来诱发冷热反应。眼震三个分量的方向在仰卧位时，十个受试者向左（10例）、向上（8例）或向下（2例），且顺时针方向（10例）。另一方面，在俯卧位时，三个分量指向右侧（10例）、向下（5例）、向上（3例），逆时针方向（10例）或不存在（2例）。这些发现表明冷热刺激同时激活了三个半规管。此外，仅靠冷热反应的对流理论无法详细解释仰卧位和俯卧位时眼震方向的变化。
