Functional properties of the descending medial longitudinal fasciculus. Gernandt BE. PMID: 5724950 [Indexed for MEDLINE] Isolated medial longitudinal fasciculus (MLF) syndrome due to infarction limited only to the midbrain is a rare occurrence. The MLF are a group of fiber tracts located in the paramedian area of 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). me·di·al lon·gi·tu·di·nal fas·cic·u·lus [TA] a longitudinal bundle of fibers extending from the upper border of the mesencephalon primarily into the cervical segments of the spinal cord, located close to the midline and anterior to the central gray matter; it is composed largely of fibers from the vestibular nuclei ascending to the motor A long discrete tract running ventrally, close to the midline, through the brainstem and upper spinal cord. With contributions from the vestibulospinal tracts, the medial longitudinal fasciculus is the main pathway by which equilibrium and balance information reaches lower motor neuron circuits to automatically adjust eye, neck, and limb movements to match sensory signals from the semicircular Abstract.

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 medial longitudinal fasciculus and the medial lemniscus pathway maintain their midline location. The medial lemniscus pathway is the most ventral of the two structures and has the internal arcuate fibers extending laterally from it. Cross section of the medulla at the level of the hypoglossal nerve (overview diagram) Objective: To review the role played by the medial longitudinal fasciculus (MLF) in ocular motor physiology and to characterize a number of syndromes that result from lesions in this eloquent brainstem tract system.

The medial longitudinal fasciculus (MLF) is a myelinated composite fibre tract found in the brainstem. The MLF primarily serves to coordinate the conjugate movement of the eyes and associated head and neck movements. 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).

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.
