The ventral posterolateral nucleus (VPL) is a nucleus of the thalamus.

Input and output

It projects to the postcentral gyrus and receives information from the spinothalamic tract and the medial lemniscus of the posterior column-medial lemniscus pathway.

The midline nuclear group (or midline thalamic nuclei) a region of the thalamus consisting of the following nuclei:
  • paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus

The anterior nuclei of thalamus (or anterior nuclear group) are collection of nuclei at the rostral end of the dorsal thalamus.

Inputs and outputs

They receive efferents from the mammillary bodies and subiculum, and project to the cingulate gyrus.
