Figure 64: The Course of the 3rd (III) Nerve | The 3rd nucleus lies at the ventral border of the periaqueductal gray matter, at the level of the superior colliculus. In between the two nuclei is the midline central caudal nucleus (CCN), which innervates bilateral levator palpebrae muscles (explaining how a unilateral nuclear 3rd can cause bilate... | Image |

Figure 65: Vascular Distribution and Anatomy (Including 3rd Nerve) of the Rostral Midbrain | In this axial section of the midbrain at the level of the superior colliculus, the paired 3rd nuclei are located ventral to the periaqueductal grey, and the midline central caudal nucleus (CCN) is located in between. The fascicles that exit the IIIrd nuclei carry the fibers destined to innervate the... | Image |

Figure 68: The Course of the 4th (IV) Nerve | The 4th nucleus lies at the ventral border of the periaqueductal gray matter, at the level of the inferior colliculus. The fascicles exit the nucleus dorsally and decussate at the anterior medullary velum (anterior floor of the fourth ventricle), and then exit the brainstem dorsally. The peripheral ... | Image |

Figure 69: Vascular Distribution and Anatomy (Including 4th Nerve) of the Caudal Midbrain | In this axial section of the midbrain at the level of the inferior colliculus, the 4th nuclei are located ventral to the periaqueductal grey, dorsal to the medial longitudinal fasciculus (MLF) and medial to the oculosympathetic tract. Fascicles exit the nucleus dorsally and decussate at the anterior... | Image |

Figure 80: Vascular Distribution and Anatomy Relevant to the Medial Medullary Syndrome | This axial section of the medulla highlights those structures that, when damaged, are often responsible for spontaneous upbeat nystagmus (UBN). The nucleus of Roller and nucleus intercalatus normally have an inhibitory influence over the cerebellar flocculus, and when there is a lesion of Roller/int... | Image |

Five Common Ocular Motor Signs in Cerebellar Disorders - Saccadic Hypermetria, Saccadic Pursuit & VOR Suppression, Gaze-evoked & Rebound Nystagmus | (1) Saccadic hypermetria - an overshoot of the visual target (2) Saccadic smooth pursuit - due to impaired pursuit and low gain, saccades are needed to keep up with the visual target. This gives it a ‘choppy' appearance. (3) Saccadic vestibulo-ocular reflex (VOR) suppression - another... | Image/MovingImage |

Gaze-Evoked and Centripetal Nystagmus in Creutzfeldt-Jakob Disease | This is a 65-year-old woman who experienced a progressive cerebellopathy over several months. Initially, she presented with mild gait imbalance and positional vertigo, and there was only apogeotropic positional nystagmus (more pronounced in supine roll test compared to Dix-Hallpike) with a very slig... | Image/MovingImage |

Gaze-evoked and Rebound Nystagmus in a Cerebellar Syndrome | 𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: 30-yo-man with the subacute onset of a cerebellar syndrome. After extensive evaluation and progression, it was thought that this represented an autoimmune process and there was some improvement with immunosuppression. He ... | Image/MovingImage |

Gaze-Evoked Nystagmus & Slow Saccades Due to Anti-GAD Antibodies in a Patient with Stiff Person Syndrome | This is a 70-year-old woman with a several year long history of imbalance and stiffness. Exam demonstrated axial and lower extremity stiffness, and ocular motor exam demonstrated gaze-evoked nystagmus (e.g., right-beating in right gaze, left-beating in left gaze, up-beating in up gaze), and mild to ... | Image/MovingImage |

Head-Shaking-Induced Nystagmus Following Ramsay Hunt Vestibulopathy | 𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 50-year-old man who experienced the abrupt onset of imbalance, dizziness and left-sided hearing loss 4 months prior to this examination. He was found to have herpetic vesicles in the left external auditory canal... | Image/MovingImage |

Hemifacial Spasm | This is a 45-year-old man with intermittent left facial twitching and eyelid closure for the last 6 months. With observation, spontaneous left facial spasms were seen involving the orbicularis oculi and oris muscles. With voluntary contraction of left facial muscles, with smiling for instance, there... | Image/MovingImage |
