Types of monocular eye movements studied by intracortical microstimulation in the cat's coronal sulcus.

To study the types of the monocular eye movements, intracortical microstimulations were applied to the fundus of the cat's coronal sulcus where the monocular movements of the contralateral eye were evoked. The monocular eye movements were saccadic and directed toward the nasal side converging on a horizontal line from various eye positions. The average threshold and latency were 18.0 microA (range 8-30 microA) and 19.5 ms (range 18-20 ms), respectively.
