The Oculomotor Nucleus (CN III, or Edinger-Westphal complex) is a midbrain cranial nerve nucleus that contains motor neurons controlling most extraocular muscles, as well as preganglionic parasympathetic neurons that regulate pupil constriction and lens accommodation. Located in the midbrain's tegmentum, this nucleus is essential for vertical gaze, conjugate eye movements, pupil reactivity, and eyelid elevation. Its dysfunction is a hallmark feature in several neurodegenerative and neurological disorders. [1]
The oculomotor nucleus is located in the midbrain's ventrolateral tegmentum, at the level of the superior colliculus. It comprises several distinct subpopulations: [2]
The oculomotor nerve supplies four of the six extraocular muscles: [3]
Inputs: [4]
Outputs: [5]
Oculomotor neurons exhibit unique properties: [6]
PSP is characterized by: [7]
PD affects the oculomotor system through:
