This echo cancellation occurs in the Dorsal Nucleus of the Lateral Lemniscus (DNLL). The internal arcuate fibers decussate and continue ascending as the contralateral medial lemniscus. It is situated between the pontine nuclei and the medial lemniscus. The VB gets inputs from the spinothalamic tract, medial lemniscus, and corticothalamic tract. The fine touch (epicritic) is conducted by fibers of the medial lemniscus. The trigeminal lemniscus is sometimes considered as the cephalic part of the medial lemniscus. The ascending bundle after the decussation is called the medial lemniscus. The ventral trigeminal tract tract is also called the anterior trigeminal lemniscus. The medial lemniscus is formed by the crossings of the internal arcuate fibers. The trigeminal lemniscus is composed of second order neuronal axons in the brainstem. Fibers leaving these brainstem nuclei ascending to the inferior colliculus rejoin the lateral lemniscus. The medial lemniscus and lateral lemniscus terminate in specific relay nuclei of the diencephalon. Sensorimotor integration is carried out by the cerebellum and by the dorsal column-medial lemniscus tract. Lemniscus means "ribbon", so named because the medial lemniscus "spirals" or "turns" as it ascends. The posterior column-medial lemniscus pathway is responsible for carrying information involving fine, discriminative touch.
