The pulvinar is the caudal-most nucleus of the thalamus. The pulvinar is usually grouped as one of the lateral thalamic nuclei.

Divisions
It is conventionally divided into oral, inferior, lateral, and medial subnuclei.
- The lateral and inferior pulvinar have widespread connections with visual cortical association areas.
- The oral pulvinar predominantly has connections with somatosensory cortical association areas.
- The medial pulvinar has widespread connections with cingulate, posterior parietal, and prefrontal cortical areas.
Pathology
Lesions of the pulvinar can result in neglect syndromes and attentional deficits.
