Fixation movements of the eyes.Anterior to this, the medial longitudinal fasciculus can be seen.
Usually this indicates ipsilateral spinocerebellar pathway involvment (a lateral structure).The medial longitudinal fasciculus is a key structure for conjugate horizontal eye movements by relaying signals.The medial longitudinal fasciculus (mlf) is an area of crossed over tracts, on each side of the brainstem.these bundles of axons are situated near the midline of the brainstem.they are made up of both ascending and descending fibers that arise from a number of sources and terminate in different areas, including the superior colliculus, the vestibular nuclei, and the cerebellum.
The medial longitudinal fasciculus (mlf) is organized as a pair of white matter fiber tracts that extend through the brainstem and lie near the midline just ventral to the fourth ventricle (in the medulla and pons) and cerebral aqueduct (in the midbrain).Horizontal and vertical saccades in horizontal saccades, the eyes move horizontally
This pathway is less well understood.From the vertical semicircular canals, primary afferents from cn viii synapse on the vn and ascend into the medial longitudinal fasciculus (mlf) and brachium conjunctivum (not shown) to contact the cn iii and cn iv nuclei and the interstitial nucleus of cajal (inc).However, in this case we know that the midbrain is affected (cn3 palsy) and the red nucleus lies in the medial midbrain just lateral to the cn3 nerve fascicle.

The Minnesota Twins placed utility player Austin Martin on the 10-day injured list on Sunday because of a right oblique strain.
In a corresponding move, the Twins recalled outfielder Matt Wallner from Triple-A St. Paul. Waller started in left field during Sunday's 3-2 win over the Astros, going 1-for-1 with a walk.
Martin has not played since Friday. The move is retroactive to Saturday.
The 25-year-old Martin made his major league debut on March 30 and is hitting .265 with nine doubles, one home run, nine RBIs, a .372 slugging percentage and .331 on-base percentage in 113 at-bats over 47 games.
Martin has played in the outfield, at second base and as the designated hitter.
