In rat, the VNLL is composed of two subdivisions, the ventral columnar and dorsal non columnar regions. The medial lemniscusalso known as Reil’s band or Reil’s ribbonis a large ascending bundle of heavily myelinated axons that decussate in the brainstemspecifically in the medulla oblongata.
LEMNISCO – Definition and synonyms of lemnisco in the Spanish dictionary
Lmenisco showing the course of the fibers of the lemniscus; medial lemniscus in blue, lateral in red. The medial lemniscus is formed by the crossings of the internal arcuate fibers. In rat, the DNLL has a prominent columnar organization.
Surface Cerebellopontine angle Superior medullary velum Sulcus limitans Medial lennisco Facial colliculus. Sound in the contralateral ear leads to the strongest responses in the VNLL, which deals with some temporary processing. Physiology of balance and hearing.

A modest number of GABA-stained neurons are arranged in small groups, generally in the center of the nucleus, whereas glycine-stained neurons are more common and widely dispersed, with regional concentrations in the dorsolateral and ventrolateral portions of the nucleus. Coronal section lemnieco mid-brain.

Lateral lemniscus Lateral lemniscus in red, as it connects the cochlear nucleussuperior olivary nucleus and the inferior colliculus. VNLL cells have little spontaneous activity, broad and moderately complex tuning curves; they have both phasic and tonic responses and are involved in temporal processing.

Medial lemniscus – Wikipedia
Retrieved from ” https: Sensory axons transmitting information from the head and neck via the trigeminal nerve synapse at the ventral posteromedial nucleus of the thalamus. After neurons carrying proprioceptive or fine touch information synapse at the gracile and cuneate nuclei, axons from secondary neurons decussate at the level of the medulla and travel up the brainstem as the latfral lemniscus on the contralateral opposite side.
The lateral lemniscus is a tract of axons in the brainstem that carries information about sound from the cochlear nucleus to various brainstem nuclei and ultimately the contralateral inferior colliculus of the midbrain.

The axons of the nucleus gracilis and leminsco cuneatus in the medial lemniscus have cell bodies that lie lemjisco. The internal arcuate fibers are composed of axons of nucleus gracilis and nucleus cuneatus.
