effects of direction on saccadic eye movement parameters

ABSTRACT

The present study obtained saccadic eye movements form 25 right-handed normal subjects [aged 18 to 35 yrs., mean 22.4 yrs], to examine the effects of saccade direction on the saccadic parameters [latency, duration and average velocity]. The binocular saccadic eye movement were recorded with a direct-current electro-oculographic system, and analysis was performed on a laboratory digital computer. The LED larget positions were randomly selected 10, 15, 20, 25 and 30 degrees to the left or the right of the fixation points. Generally, mean values of the saccadic parameters over a large saccade angles were in agreement with those previously reported. These were no significant difference between saccades directed to the right and the left when all saccadic parameters were analyzed statistically
