parvocellular oculomotor nucleus
Nucleus that is part of the oculomotor nerve complex consisting of preganglionic parasympathetic neurons situated close to the midline at the level of the superior colliculus (Heimer, the Human Brain and Spinal Cord, 1994, pg 244) [ ]

NIFSTD places this in oculomotor nuclear complex but this conflicts with disjointness axioms from MBA, as well as location described in Wikipedia, and is not supported in any other ontology
The Edinger-Westphal nucleus supplies preganglionic parasympathetic fibers to the eye, constricting the pupil, accommodating the lens, and convergence of the eyes. It has also been implicated in the mirroring of pupil size in sad facial expressions[WP]

The paired nuclei are posterior to the main motor nucleus (oculomotor nucleus) and anterolateral to the cerebral aqueduct in the rostral midbrain at the level of the superior colliculus. It is the most rostral of the parasympathetic nuclei in the brain stem.[WP]
