Eye movements induced after unilateral electrical stimulation to the mesencephalic reticular formation, rostral portion of the pontine reticular formation and surrounding area were investigated in thirty adult pigmented rabbits. Under pentobarbital anesthesia, electrical stimulation of pulse trains was applied through a bipolar stainless steel electrode inserted stereotaxically in the brain.
The majority of the effects were horizontal conjugate deviations, which were usually ipsilateral to the mesencephalic reticular formation, but contralateral to the rostral portion of the pontine recticular formation.
At the level of the oculomotor nuclei in the mesencephalic reticular formation, horizontal deviations were elicited to either side. It appears that oculomotor decussation for horizontal eye movement occurs at the level of the oculomotor nuclei in the mesencephalic reticular formation in rabbits.
