LEMNISCO – Definition and synonyms of lemnisco in the Spanish dictionary

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.

Red nucleus Rostral interstitial nucleus of medial longitudinal fasciculus Parabrachial area. Superior salivary nucleus Inferior salivary nucleus. The two lemnisci communicate via the commissural fibers of Probst. The temporal responses are significantly different from cells of the VNLL.

Superior cerebellar peduncle Decussation Interpeduncular fossa. General Auditory system Bone conduction Otoacoustic emission Tullio phenomenon.

It is also involved in the acoustic startle reflex; the most likely region for this latersl the VNLL.

INLL also has little spontaneous activity and broad tuning lemniscp. 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.

Lsteral distinct, primarily inhibitory, cellular groups are located interspersed within these fibers, and are thus named the nuclei of the lateral lemniscus.

Lateral lemniscus – Wikipedia

It is part of the posterior column-medial lemniscus pathwaywhich transmits touch, vibration sense, as well as the pathway for proprioception.

Trapezoid body Trigeminal lemniscus Dorsal trigeminal tract Ventral trigeminal tract Medial lemniscus Lateral lemniscus Medial longitudinal fasciculus Vestibulo-oculomotor fibers Anterior trigeminothalamic tract Central tegmental tract. The nucleus is primarily GABAergic, [1] and projects bilaterally to the inferior colliculusand contralaterally to the DNLL, with different populations of cells projecting to each IC.

Lateral lemniscus

This structure is greatly hypertrophied in the rat, forming a prominent bulge on the surface of the brainstem. GABAergic axon terminals form dense groups surrounded by GABA-lemniscal fibers throughout the nucleus, and synapse on both somata and in the neuropil.

The medial lemniscus is part of the dorsal column—medial lemniscus pathwaywhich ascends from the skin to the thalamus[1] which is important for somatosensation from the skin and joints, therefore, lesion of the medial lemnisci causes an impairment of vibratory lemnjsco touch-pressure sense.
