Pulvinar projects to?

Pulvinar projects to?

• A. Prefrontal cortex
• B. Brainstem
• C. Parietal, occipital, and temporal lobes
• D. Primary motor cortex

Answer: (C)

The pulvinar serves as a high-level visual relay hub in the dorsal thalamus, coordinating processing across cortical visual areas. It receives input from the visual pathway and the superior colliculus and sends outputs to the posterior cortical association regions—the parietal, occipital, and temporal lobes. This arrangement lets the pulvinar synchronize activity across these areas, supporting visual attention, feature integration, and cross‑modal coordination. It isn’t primarily projecting to the brainstem or the primary motor cortex, which are more closely connected with other thalamic nuclei and circuits. While there are connections to prefrontal areas as part of broader thalamocortical networks, the strongest and most characteristic projections are to the parietal, occipital, and temporal lobes.
