Exploration of the cerebellum from above and behind
Medial lemniscus within medulla and pons
The medulla and pons have been dissected to a deeper level on the right side. The medial lemniscus can be traced from its origin in the decussation of the medial lemniscus (20) upward through the medulla as a vertical band near the midline (19). In the pons this band becomes flattened and displaced laterally and is interwoven with the transverse fibers of the trapezoid body (16) which cross the midline. Above this the lemniscus gradually comes to lie in a more lateral position (13).
