Non-conjugate monocular optokinetic nystagmus in cats.
Binocular eye movement during horizontal monocular optokinetic nystagmus was studied in cats. When the stimulus pattern was moved slowly (at 1-10 deg/sec in temporonasal direction and 1 deg/sec in nasotemporal, averages of four cats), the gain (slow phase velocity/stimulus velocity) of the covered eye was significantly lower than that of the seeing eye. At the faster stimulus velocities, these differences of gain decreased.
