Pulvinar Nuclei - Divisions

Divisions

It is conventionally 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.

• 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, as well as the regulation of visual attention
