RT Journal Article SR Electronic T1 Selective loss of small myelinated fibers in the lateral corticospinal tract due to midbrain infarction JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 588 OP 591 DO 10.1212/WNL.47.2.588 VO 47 IS 2 A1 Terao, S.

YR 1996 UL http://n.neurology.org/content/47/2/588.abstract AB Small myelinated fibers in the lateral corticospinal tract (LCST) were selectively diminished as compared with large myelinated fibers in a patient with an old paramedian midbrain infarct involving the red nuclei, oculomotor nuclei, and inferior olivary pseudohypertrophy.Although the physiologic function of small myelinated fibers in the LCST is unknown in humans, we hypothesize that some of these fibers may include the rubrospinal tract.
