-
The axons of the lower nucleus of the lateral lemniscus, which arise from the larger stellate or spindle-shaped cells, with long, smooth, much branched dendrites, are said by some authors to join the lateral lemniscus, but according to Cajal they pass medially toward the raphé; their termination is unknown.
IX. Neurology. 4e. Composition and Central Connections of the Spinal Nerves
-
The lateral and ventral spinothalamic fasciculi are sometimes termed the secondary sensory fasciculus or spinal lemniscus.
IX. Neurology. 3. The Spinal Cord or Medulla Spinalis
-
The medial longitudinal fasciculus retains its paramedian position, and the central tegmental tract is surrounded by the loose substance of the reticular formation, situated dorsal to the medial lemniscus.

IX. Neurology. 4e. Composition and Central Connections of the Spinal Nerves
-
In the brain-stem the fibers run lateral from the inferior olive, ventro-lateral from the superior olive, then ventro-medial from the spinal tract of the trigeminal; the fibers come to lie in the medial portion of the lateral lemniscus.
IX. Neurology. 3. The Spinal Cord or Medulla Spinalis
-
In the upper part of the lateral lemniscus there is a collection of nerve cells, the nucleus of the lateral lemniscus, around the cells of which some of the fibers arborize and from the cells of which axons originate to continue upward the tract of the lateral lemniscus.
IX. Neurology. 5h. The Acoustic Nerve
-
Ascending from the medulla and curving dorsolaterally into the tegmentum of the midbrain is the medial lemniscus, on its way to the thalamus.
-
In the pons it lies along the lateral edge of the lateral lemniscus.
IX. Neurology. 3. The Spinal Cord or Medulla Spinalis
-
At the medullary level, the medial lemniscus (which contains the 2nd neuron axons in the pathway for proprioceptive and tactile sensations) is found dorsal to the pyramidal tract and medial to the olivary nucleus.
-
This part of the lateral lemniscus is known as the fillet of Reil.
IX. Neurology. 4e. Composition and Central Connections of the Spinal Nerves
-
A thin, transversely oriented ribbon of fibers, the medial lemniscus, ascends from the lower brainstem into the midbrain tegmentum where it occupies a ventrolateral position.

IX. Neurology. 4e. Composition and Central Connections of the Spinal Nerves
-

IX. Neurology. 4b. The Mid-brain or Mesencephalon
-
The lateral lemniscus (lateral fillet), the continuation upward of the central path of hearing, consists of fibers which come from the cochlear nuclei of the same and the opposite side by way of the trapezoid body and from the preolivary nuclei.
IX. Neurology. 4e. Composition and Central Connections of the Spinal Nerves
