Miniature eye movements of fixation in rhesus monkey

Abstract Two-dimensional eye movements were recorded from four rhesus monkeys during training on two tasks aimed at showing they were capable of as accurate fixation control as man. Extensive training on a difficult acuity/vigilance problem caused only three monkeys to occasionally fixate the display for periods over 10 sec with stability of eye position comparable to man. Changing the task to directly reward monkeys for keeping targets within a criterion distance of the fovea increased numbers of long fixations and produced human-like fixation stability in all four monkeys. Monkeys, like man, used slow control to maintain fixation.
