inferior pulvinar nucleus

inferior pulvinar nucleus (IPul)

The term inferior pulvinar nucleus refers to one of four subdivisions of the pulvinar defined on the basis of cyto-myeloarchitecture in the human ( Carpenter-1983 ) and the macaque ( Olszewski-1952 ). In the macaque it is very cellular, with most cells of the kind Olszewski found typical of the pulvinar: lightly-stained, medium-sized, multipolar, and plump. In addition he found a second small but distinct and scattered population of larger, darker cells. The inferior pulvinar nucleus is one of four subdivisions of the pulvinar. The others are the medial pulvinar nucleus, the lateral pulvinar nucleus and the anterior pulvinar nucleus. None is found in the rodent ( Swanson-2004 ).

Also known as: inferior pulvinar nucleus, Nucleus pulvinaris inferior, Nucleus pulvinaris thalami, pars inferior, Nucleus pulvinaris inferior thalami

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
