Where is the Edinger-Westphal nucleus located?

Explanation:
The Edinger-Westphal nucleus is the parasympathetic part of the oculomotor nerve complex, giving preganglionic fibers that synapse in the ciliary ganglion to control pupil constriction and lens accommodation. Its neurons reside in the rostral (upper) midbrain, near the cerebral aqueduct and adjacent to the oculomotor nucleus. This location places it in the upper midbrain, not in the pons or medulla.
