Latency and duration of eye movements in the horizontal plane.

The electrical method of eye movement recording (EOG) was used to study the reactions of the eyes when subjects attempted to fixate as quickly as possible on light stimuli appearing at various points along the horizontal plane. Each eye was recorded separately, allowing an assessment of the degree of independence of the eyes when reacting in this way. In addition to the data concerning latency of ocular reactions and the duration of eye movements, information regarding the relative speed of movements from periphery to center as compared to movements from center to periphery was obtained. It was also found that the two eyes tend to act independently in regard to latency and speed of movement when moving toward peripheral stimuli.
