Ocular exposure to blue-enriched light has an asymmetric influence on neural activity and spatial attention

Links

Summary

Blue-enriched light exposure was found to asymmetrically modulate neural activity and spatial attention networks in healthy volunteers, suggesting that lighting spectrum influences not just global alertness but also lateralized cognitive functions. These findings are relevant for lighting design in workplaces or environments where sustained attention and spatial awareness are critical.

Key Findings

Blue-enriched light exposure produced asymmetric effects on neural activity associated with spatial attention orienting, suggesting hemisphere-specific modulation.
Results indicate that blue-enriched lighting directly manipulates alertness-related brain networks, with downstream effects on attentional performance.
The study demonstrates a functional interaction between light-driven alertness systems and spatial attention networks in the human brain.
