Lateral lemniscus

The function of the complex of Nuclei of the lateral lemniscus is not known; however it has good temporal resolution compared to other cells higher than the cochlear nuclei and is sensitive to both timing and amplitude changes in sound.

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 le,nisco opposite side. The two lemnisci communicate via the commissural fibers of Probst.

Three distinct, primarily inhibitory, cellular groups are located interspersed within these fibers, and are thus named the nuclei of the lateral lemniscus. The medial lemniscus is labeled VNLL cells have little spontaneous activity, broad and moderately complex tuning curves; they have both phasic lemnlsco tonic responses and are involved in temporal processing.
