Lateral pulvinar nucleus (nucleus pulvinaris lateralis) is one of four traditionally anatomically distinguished nuclei of the pulvinar of the thalamus. The other three nuclei of the pulvinar are called anterior, inferior and medial pulvinar nuclei.
Connections
Afferent
- Lateral pulvinar nucleus, together with its inferior and medial nuclei, receives afferent input from superior colliculus.[1][2]
- The dorsal part of the lateral
Efferent
- Lateral pulvinar nucleus, together with its inferior nucleus, both have projections to the early visual cortical areas.[1][2]
- The dorsal part of the lateral
Functions
- Lateral pulvinar nucleus, together with its inferior and medial nuclei, is thought to be important for the initiation and compensation of saccadic movements of the eyes.[1][2] Those nuclei also participate in the visual attention regulation.[3][4]
Clinical significance
Lesions of the lateral
attentional deficits.[5]
