Summary: The lower motor center of the rat extraocular muscles was studied using the fluorescent double labeling techique. Double labeled neurons were observed in the oculomotor nucleus between the inferior rectus and levator palpebrae superioris, the superior rectus, the medial rectus, the inferior rectus, the inferior oblique, the lateral rectus and the superior oblique. Several combinations of several muscles showed the existence of double labeled neurons in the trochlear nucleus and the accessory abducens nucleus.
