Sound in the contralateral ear leads to the strongest responses in the VNLL, which deals with some temporary processing.
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.
It is part of the posterior column-medial lemniscus pathwaywhich transmits touch, vibration sense, as well as the pathway for proprioception. Retrieved from ” https: Anatomy of the medulla.
Núcleo posterior do lemnisco lateral
Anatomical terms of neuroanatomy [ edit on Wikidata ]. Spinotectal tract Central tegmental tract. It is also involved in the acoustic startle reflex; the most likely region for this being the VNLL.
Brain and spinal cord: Surface Cerebellopontine angle Superior medullary velum Sulcus limitans Medial eminence Facial colliculus.
The medial lemniscus is part of the dorsal column—medial lemniscus pathwaywhich ascends from the skin to the thalamus which is important for somatosensation from the skin and joints, therefore, lesion of the medial lemnisci causes an impairment of vibratory and touch-pressure sense.

Medial lemniscus – Wikipedia
Horizontal section through the lower part of the pons. Anatomy of the pons. Red nucleus Rostral interstitial nucleus of medial longitudinal fasciculus Parabrachial area.
INLL also has little spontaneous activity and broad tuning curves.
The PRF descends the reticulospinal tract where it innervates motor neurons and spinal interneurons. Vestibular cortex Vestibulo-oculomotor fibers. The medial lemniscus is formed by the crossings of the internal arcuate fibers.
Lateral lemniscus in red, as it connects the cochlear nucleussuperior olivary nucleus and the inferior colliculus. Auditory system Bone conduction Otoacoustic emission Tullio phenomenon. General Auditory system Bone conduction Otoacoustic emission Tullio phenomenon.
Vestibular nuclei Medial vestibular nucleusLateral vestibular nucleus cerebellum: The internal arcuate fibers are composed of axons of nucleus gracilis and nucleus cuneatus. 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 medial lemniscus on the contralateral opposite side.
From Wikipedia, the free encyclopedia. Pyramid Anterior median fissure Anterolateral sulcus Olive Inferior olivary nucleus. The cells of the DNLL respond best to lxteral inputs, and have onset and complexity tuned sustained responses.
