The ventral posterolateral nucleus (VPL) is a nucleus of the thalamus. Together with the ventral posteromedial nucleus (VPM), ventral posterior inferior nucleus (VPI) and ventromedial posterior nucleus (VMpo), it constitutes the ventral posterior nucleus. There is uncertainty in the location of VMpo, as determined by STT terminations and staining for calcium-binding proteins, and several authorities do not consider its exstence as being proved (Willis et al The Journal of Pain 2002;3:79-94; Graziano and Jones, The Journal of Neuroscience 2004;24:248–256.

Input and output[edit]

The VPL receives information from the neospinothalamic tract and the medial lemniscus of the posterior column-medial lemniscus pathway. It then projects this sensory information to Brodmann's Areas 3, 1 and 2 in the postcentral gyrus. Collectively, Brodmann areas 3, 1 and 2 make up the primary somatosensory cortex of the brain.
