Abstract
Horizontal mono-ocular movements were recorded by electronystagmography. Saccades caused by alternative gazing at two targets with a 10 degree visual angle, caloric nystagmus and optokinetic nystagmus were recorded and the eye velocity recordings were measured.
Eye velocity recordings showed that inward movements of the right or left eye were either faster than outward, or were equal. These phenomena were remarkable in saccadic movements of 10 degrees and in cases of caloric nystagmus, however, such were not remarkable in the case of optokinetic nystagmus.
