"Unveiling the Brain's Response to Blue Light: Insights from Ultrahigh-field MRI"

Researchers at the University of Liège have used ultrahigh-field MRI to investigate how blue light stimulates the brain. They found that exposure to blue-enriched light strengthened the connectivity between the posterior thalamus and the intraparietal sulcus, an attentional-related area of the cortex. This modulation of information flow from subcortical to cortical areas suggests that blue light affects non-visual cognitive activity. The study provides empirical data supporting the impact of blue light on brain function and highlights the role of the thalamus in relaying non-visual light information.
