Coronal Section of the Brainstem Showing Ocular Motor Nuclei and Anatomy of the Vestibular Nucleus (with SCC Inputs) | (A) Seen here is a coronal view of the brainstem showing the locations of the ocular motor nuclei (IIIrd, IVth, VIth) as well as the nuclei of VII and VIII (vestibular and cochlear). The vestibular nucleus (VN) is divided into the inferior, lateral, medial, and superior subnuclei, and the medial ves... | Pons; Medullar OMS; Mesencephalon OMS; Figures |

Medullary Structures Relevant to Upbeat Nystagmus | This is an axial section of the medulla, slightly more caudal as compared to (please refer to figure "medullary structures relevant to the ocular motor and vestibular consequences of the lateral medullary (Wallenberg) syndrome). Again seen are the inferior cerebellar peduncle (ICP) and caudal aspect... | Medulla OMS; Figures |

Medullary Structures Relevant to the Ocular Motor and Vestibular Consequences of Lateral Medullary (Wallenberg) Syndrome | This is an axial section of the medulla showing the structures that, when damaged, are responsible for the vestibular and ocular motor features of the lateral medullary or Wallenberg syndrome. The nucleus prepositus hypoglossi (NPH) and medial vestibular nucleus (MVN) complex is important for horizo... | Medulla OMS; Figures |

Saccadic Pathways in the Brainstem and Cerebellum & Mechanism for Saccadic Dysmetria in Wallenberg Syndrome - Abnormal Function of the Brainstem/Cerebellar Saccadic Pathways with a Left Wallenberg Syndrome | The end result of a lesion involving the climbing fibers within the left lateral medulla is deficient rightward saccades (contralesional hypometric saccades), and over-active leftward saccades (ipsilesional hypermetric saccades), and ipsilesional ocular lateropulsion given this baseline imbalance. M... | Medulla OMS; Normal Saccades; Abnormal Saccades; Figures |

Saccadic Pathways in the Brainstem and Cerebellum & Mechanism for Saccadic Dysmetria in Wallenberg Syndrome - Normal Function of the Brainstem/Cerebellar Saccadic Pathways | The inferior cerebellar peduncle (ICP) carries climbing fibers to the dorsal vermis, and these fibers have an inhibitory influence over the Purkinje cells. These Purkinje cells normally inhibit the ipsilateral fastigial nucleus, and the fastigial nucleus projects to the contralateral inhibitory burs... | Medulla OMS; Normal Saccades; Abnormal Saccades; Figures |
