Ventral posterolateral nucleus
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".Script error: No such module "Check for unknown parameters". The ventral posterolateral nucleus (VPL) is one of the subdivisions of the ventral posterior nucleus in the ventral nuclear group of the thalamus.[1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the dorsal column-medial lemniscus pathway) which synapse with the third-order neurons in the nucleus. These then project to the primary somatosensory cortex in the postcentral gyrus.[2]Script error: No such module "Unsubst".
There is uncertainty regarding the location of VMpo (posterior part of ventral medial nucleus), as determined by spinothalamic tract (STT) terminations and staining for calcium-binding proteins, and several authorities do not consider its existence as being proved.[1][3]
The term "ventral posterolateral nucleus" was introduced by Le Gros Clark in 1930.[4][5]
Anatomy
Subdivisions
The oral part of the ventral posterolateral nucleus (nucleus ventrointermedius) in the human, (VPLO)[6] is a subdivision of the VPL with projections to the motor cortex.[7]
There is also a caudal part of the ventral posterolateral nucleus (VPLC).[8]
