The lateral posterior nucleus is a nucleus of the thalamus. It represents the rostral continuation of the pulvinar (with which it shares comparable connections - the two may be considered a complex). It is thought to be involved in complex sensory integration.

Anatomy

Connections

Additional connections include the: inferior parietal lobule, cingulate cortex, and medial portion of parahippocampal gyrus.

Afferents

Afferents of the LPN project from the: occipital lobe, precuneus, superior parietal lobule, pretectal area, and superior colliculus.

Efferents

The LPN issues efferents to the precuneus, superior parietal lobule, temporal lobe, and visual association area.

Other animals

In rodents, the lateral posterior nucleus is considered the homologue of the primate pulvinar.
