The pulvinar nuclei (nuclei pulvinares) are a collection of nuclei located in the pulvinar thalamus. The pulvinar part is the most posterior region of the thalamus.
The pulvinar is usually grouped as one of the lateral thalamic nuclei in rodents and carnivores, and stands as an independent complex in primates. The word is derived from the Latin pulvinus for "cushion". In Ancient Roman religion a pulvinar was an "empty throne" or cushioned couch for occupation by a deity.
