Abstract Saccadic eye movement system performance was investigated to determine whether neurosensory and motor system function is improved by training. There were 2 populations studied--12 Air National Guard pilots, individuals with extensive visual training, and 12 nonpilots. Each subject executed 54 saccadic eye movements while tracking an LED target which moved at random from one location to another. The target display consisted of nine small LED's, each separated by 5 degrees. The ordering of the target movements, as well as the time interval between target movements, were randomized. Horizontal saccadic eye movements were recorded from infrared signals reflected from the anterior surface of the cornea. Signals for bilateral tracking were digitized using an analog-to-digital converter and stored in the hard disk of an IBM/XT. Results using advanced digital processing techniques indicate no significant differences in neurosensory and motor system function during saccadic eye movements between the two populations. A time-optimal central nervous system control mechanism is described which cannot be improved upon by training or exercise.
