lateral lemniscus การใช้
- Lateral lemniscus is the first point of integration of sound and pain information.
- Fibers leaving these brainstem nuclei ascending to the inferior colliculus rejoin the lateral lemniscus.
- This echo cancellation occurs in the Dorsal Nucleus of the Lateral Lemniscus ( DNLL ).
- Additional projection targets include the dorsal and ventral nuclei of the lateral lemniscus ( DNLL & VNLL ).
- The lateral lemniscus is located where the cochlear nuclei and the pontine reticular formation ( PRF ) crossover.
- The majority of the ascending fibers from the lateral lemniscus project to IC, which means major ascending auditory pathways converge here.

- The axons from the MSO continue to higher parts of the pathway via the ipsilateral lateral lemniscus tract . ( Yost, 2000)
- 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 ).
- 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 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.
- 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.
- After nerves from the cochlear nucleus cross over in the trapezoid body and go on to the superior olivary nucleus, they continue to the lateral lemniscus, then the inferior colliculus, then the medial geniculate body, before finally arriving at the primary auditory cortex.
