WOROI: 236 - Pulvinar

The posterior part of the thalamus. The Mai atlas has 6 nuclei for the pulvinar: oralis, medialis, ventralis, lateralis, superficialis and intergeniculatus as well as a seventh area the 'diffuse pulvinar'.

Abbreviation: Pul

Variation: Nucleus pulvaris
Variation: Pulvinar nucleus
Variation: Nucleus pulvinaris thalami

Subcortical activations were found in cerebellum (particularly the vermis) and in the thalamus with the focus in a region comprising the lateral geniculate nucleus, the pulvinar, and adjacent parts of the reticular nucleusClaus Bundesen; Axel Larsen; Soren Kyllingsbaek; Olaf B.
