Component items:

• Oculomotor Nucleus (LPC.MM.OCN): Change Eye Direction
• Trochlear Nucleus (LPC.MM.TRH): Control superior oblique muscles of eyes
• Edinger-Westphal Nucleus (LAC.MM.EWN): Change Eye Pupil
• Mesencephalic Trigeminal Nucleus (LPC.MM.MSTR): unconscious proprioception from muscle spindles; facial somatic sensations from muscles of mastication, monosynaptic masticatory reflex
