lemniscal

The nuclei corresponding to the lemniscal territory are called VP.

Also, it does not receive lemniscal afferent and is thus not a part of VC.

This processing is known colloquially as "fast and dirty" rather than the "slow and accurate" system of classical or lemniscal system.

Further conduction in the posterior columns passes through the synapse at the cervicomedullary junction and enters the lemniscal decussation.

There are relatively direct, 'lemniscal' pathways from the receptors to the cortex and other, less direct, routes that involve largely subcortical relays.

Starting from these nuclei, axons go ventralwards and decussate (to the other side) still in the medulla oblongata forming the "lemniscal decussation".

Deep lemniscal territory VPO (or VPS)

Lateral lemniscus (LL) and lemniscal nuclei (LN) - Ipsilateral and contralateral stimulation.

Neurons from the nucleus laminaris project to the core of the central nucleus of the inferior colliculus and to the anterior lateral lemniscal nucleus.

Excitatory inputs to the VB are medial lemniscal (ML) and corticothalamic (CT) glutamatergic synapses.

In the sound level pathway, the posterior lateral lemniscal nucleus (mammalian lateral superior olive) is the site of binaural convergence and where IID is processed.

Below L3, relevant neurons pass into the fasciculus gracilis (usually associated with the dorsal column-medial lemniscal system) until L3 where they synapse with Clarke's nucleus (leading to considerable caudal enlargement).

While the neurons for touch sensations ascend ipsilaterally through the dorsal column-medial lemniscal system to the thalamus; neurons for pain and temperature ascend contralaterally to the thalamus through the anterolateral system.

When CT synaptic transmission is decreased by activation of the nAChRs then the activated nAChRs in the VB can selectively enhance information to the somatosensory cortex through the medial lemniscal tract.

The degree of excitation and inhibition depends on sound pressure, and the difference between the strength of the inhibitory input and that of the excitatory input determines the rate at which neurons of the lemniscal nucleus fire.

The most important of these pathways for our purposes is the lemniscal pathway, in which axons from the principal nucleus cross over and project to "barreloids" in the dorsomedial section of the ventroposterior medial nucleus (VPMdm) of the thalamus.

Starting from caudally one may describe the lemniscal territory, made up of two components cutaneous or tactile and deep (musculoarticular), the cerebellar territory also made up of two nuclei, the pallidal territory and the nigral territory .
