The pulvinar is the caudal-most nucleus of the thalamus that 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.
Lesions of the pulvinar can result in neglect syndromes and attentional deficits.
The Pulvinar is usually grouped as one of the lateral thalamic nuclei.
