The pulvinar nuclei (nuclei pulvinaris) are a collection of nuclei located in the pulvinar 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. ==Structure== By convention, it is divided into anterior, inferior, lateral, and medial subdivisions, each containing multiple nuclei. * The ''lateral'' and ''inferior'' pulvinar have widespread connections with early visual cortical areas. * The dorsal part of ''lateral'' pulvinar predominantly has connections with posterior parietal cortex and the dorsal stream cortical areas. * The ''medial'' pulvinar has widespread connections with cingulate, posterior parietal, premotor and prefrontal cortical areas.〔C. Cappe, A. Morel, P. Barone & E.M. Rouiller (2009). The thalamocortical projection systems in primate: an anatomical support for multisensory and sensorimotor interplay. Cerebral Cortex, 19(9), 2025-2037〕 * The pulvinar also has input from the superior colliculus to ''inferior'', ''lateral'' and ''medial'' sections, which seems to be important in the initiation and compensation of saccade,〔Berman, R., & Wurtz, R.
