Pulvinar Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The pulvinar is the largest nucleus of the thalamus, serving as a higher-order relay that integrates information from multiple sensory and cognitive networks. It plays critical roles in visual attention, spatial processing, and the coordination of cortical activity. [1]
