What are the anatomical connections between the prefrontal cortex and pulvinar?

The prefrontal cortex and pulvinar are two interconnected brain regions that play critical roles in cognition and sensory processing. The prefrontal cortex, located in the frontal lobe, is involved in executive functions such as decision-making, attention, and problem-solving. On the other hand, the pulvinar is a nuclei complex within the thalamus that functions as a relay station for visual information processing. These two regions are anatomically connected through a bidirectional pathway called the prefrontal-pulvinar circuit. The pathway consists of axonal fibers traveling from the prefrontal cortex to the pulvinar, as well as from the pulvinar back to the prefrontal cortex. This reciprocal connection allows for information exchange and collaboration between these regions, enabling the integration of sensory information with higher cognitive processes. The prefrontal-pulvinar circuit is essential for various functions, including attentional control, perception, and the modulation of emotional responses. Understanding the anatomical connections between these regions provides insights into the neural mechanisms underlying complex cognitive and sensory processes.
