The medial longitudinal fasciculus (MLF) is the final common pathway for all conjugate adducting horizontal eye movements, as well as for the vertical-torsional vestibulo-ocular reflex (VOR).

Medical definition of medial longitudinal fasciculus: any of four longitudinal bundles of white matter of which there are two on each side that extend from the

These bundles of axons are situated near the midline of the brainstem and are composed of both ascending and descending fibers that arise from a number of sources and terminate in different areas. 2008-04-22 The nucleus innervates the ipsilateral lateral rectus and sends interneurons to the medial longitudinal fasciculus (MLF) that will go on to innervate the contralateral medial rectus to coordinate horizontal gaze. The fascicle travels ventrally and exits the pontomedullary junction anterolaterally. Structure and Function The rostral interstitial nucleus of the medial longitudinal fasciculus (RI) contains the premotor burst neurons, which are essential for the generation of vertical and torsional saccades ( Büttner-Ennever et al., 1982; Vilis et al., 1989; Kremmyda et al., 2007 ). The inferior longitudinal fasciculus (ILF) is traditionally considered one of the major occipitotemporal association tracts. It is the white matter backbone of the ventral visual stream.

It descends as a component of the medial longitudinal fasciculus. It terminates by synapsing with the motor neurons present in the cervical segment of the spinal cord . Although anatomically it is a very small tract that is not even visible independently, the functions performed by the medial vestibulospinal tract are very important.

doi: 10.1007/s11682-019-00187-4. Isolated medial longitudinal fasciculus (MLF) syndrome as a result of midbrain infarction is rare, and its magnetic resonance imaging (MRI) has not been reported previously. A 62‐year‐old man suddenly presented with diplopia, and consulted JA Toride Medical Center, Ibaraki, Japan. Description. Medial longitudinal fasciculus are bundle of various fibers systems that enter and leave at different levels.Its fibers interconnect the motor nuclei of cranial nerves and also connect the vestibular apparatus with ocular muscles, neck muscles, and the extrapyramidal system. The medial longitudinal fasciculus is found in the brainstem and is a set of crossed fibers with ascending and descending fibers.

It is a motor nucleus, and so is located near the midline, embedded within the medial longitudinal fasciculus (see diagram at right). The oculomotor nerve and trochlear nerve are the only two cranial nerves with nuclei in the midbrain , other than the trigeminal nerve, which has a midbrain nucleus called the mesencephalic nucleus of trigeminal nerve , which functions in preserving dentition. The superior longitudinal fasciculus is an association fiber tract in the brain that is composed of three separate components. It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes. These bundles of axon tracts pass from the frontal lobe through the operculum to the posterior end of the lateral sulcus where they … Medial longitudinal fasciculus • A longitudinal bundle of fibers extending from the upper border of the midbrain into the cervical segments of the spinal cord, located close to the midline and ventral to the central gray matter; it is composed largely of fibers from the vestibular nuclei ascending to the motor neurons innervating the external eye muscles (abducens, trochlear, and oculomotor The PPRF is located anterior and lateral to the medial longitudinal fasciculus (MLF).

The oculomotor nerve and trochlear nerve are the only two cranial nerves with nuclei in the midbrain , other than the trigeminal nerve, which has a midbrain nucleus called the mesencephalic nucleus of trigeminal nerve , which functions in preserving dentition. The superior longitudinal fasciculus is an association fiber tract in the brain that is composed of three separate components. It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes.

Function The medial longitudinal fasciculus carries information about the direction that the eyes should move.

The optokinetic reflex is when a patient follows an object and there are both smooth and saccadic eye movements. The medial longitudinal fasciculus (MLF) is a myelinated composite fiber tract found in the brainstem. The MLF primarily serves to coordinate the conjugate movement of the eyes and associated head and neck movements.

In the ventrolateral medulla, ENK-ir neurons were distributed in a conical caudorostral column throughout the PGi.
