Pulvinar Nucleus 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, constituting approximately 25% of its volume. It plays critical roles in visual attention, spatial processing, and multimodal integration. [@laberge2004]

Overview
The Pulvinar Nucleus is the largest thalamic nuclei, serving as a critical hub for visual attention, spatial processing, and multimodal sensory integration. As the "visual attention center" of the thalamus, it coordinates information flow between the visual [cortex](/brain-regions/cortex), parietal cortex, and frontal eye fields. The pulvinar is particularly vulnerable in [Alzheimer's disease](/diseases/alzheimers-disease), where atrophy correlates with visual processing deficits, and in [Parkinson's disease](/diseases/parkinsons-disease), where it contributes to saccadic abnormalities and visual hallucinations. It is also implicated in schizophrenia, where altered pulvinar connectivity contributes to attentional deficits. [@robinson1992]
