[Alternating optokinetic nystagmus (OKN) elicited by dichoptically presented moving grating stimuli in normal and unilateral labyrinthectomized rabbits].
Optokinetic responses to two dichoptically presented grating moving in opposite directions were investigated in normal and unilateral labyrinthectomized rabbits. In normal rabbits, OKN took place alternatively, while in unilateral labyrinthectomized rabbits, alternating OKN still took place only with some irregularity. These results indicate that OKN in rabbit to dichoptic stimulation is alternately controlled by the velocity information coming from the left and the right eye, a fact suggesting that the switching center of the control system locates somewhere behind the point of binocular summation in the central nervous system.
