Secondary axons from the medial lemniscus finally terminate in the ventral posterolateral nucleus ( VPL ) of the thalamus, where they synapse with tertiary neurons.
32.
It is part of an ascending pathway that is important for well-localized fine touch and conscious proprioception called the posterior column-medial lemniscus pathway.

34.
The medial lemniscus carries axons from most of the body and synapses in the ventral posterolateral nucleus of the thalamus, at the level of the mamillary bodies.
35.
Because the posterior column medial lemniscus pathway travels through and relays information to these areas, a lack of proper sensation indicates a problem with this neural sensory tract.
36.
The spinothalamic tract, like the dorsal column-medial lemniscus tract, uses three neurons to convey sensory information from the periphery to conscious level at the cerebral cortex.
37.
Ventral nuclei of lateral lemniscus help the inferior colliculus ( IC ) decode amplitude modulated sounds by giving both phasic and tonic responses ( short and long notes, respectively ).
38.
The name comes from the two structures that the sensation travels up : the posterior ( or dorsal ) column of the spinal cord, and the medial lemniscus in the brainstem.
39.
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.
40.
The lateral lemniscus has three nuclei : dorsal nuclei respond best to bilateral input and have complexity tuned responses; intermediate nuclei have broad tuning responses; and ventral nuclei have broad and moderately complex tuning curves.
